11. Hence, the investigators concluded, it was clear that a current could be started in the selenium by the action of the light alone.5 They felt confident that they had discovered something completely new: that light caused a flow of electricity through a solid material. The first "real" working solar module was built in 1883 by Charles Edgar Fritts, an American inventor, who constructed modules by coating a wide plate of copper with selenium and then topped it with an extremely thin semi-transparent layer of gold leaf. It was in 1883 that the first cell was built by Charles Fritts. 1977: The world production of photovoltaic cells exceeds 500 kW. Placing a commercial selenium cell in sunlight, he recorded that the cell produced 4.9 watts per square meter. Become an APS Member On a Heuristic Viewpoint Concerning the Production and Transformation of Light. Annalen der Physik, vol. 2009: The American Recovery and Reinvestment Act (ARRA) provides $90 billion in clean energy investments and tax incentives, including subsidies and loan guarantees for solar energy projects. Adams, W. G. and R. E. Day. In 1887, German physicist Heinrich Hertz discovered the photoelectric effect, which refers to the emission of electrons when light hits a material. In the late 1880s, he turned his attention to the study of solar power, and he began experimenting with ways to harness the suns energy and convert it into electricity. National Renewable Energy Laboratory, 2008. Material Sciences and Applications, vol. W Smith, The action of light on selenium, 2 J Soc Tel Engrs 27-29 (1873). 113-117. At the time of his baptism, Charles received the . Originally printed in Intellectual Property Magazine on April 27, 2020. Wiki-Solar, Utility-scale solar in 2018: Still growing thanks to Australia and other later entrants,https://wiki-solar.org/library/public/190314_Utility-scale_solar_in_2018.pdf(14 Mar 2019). Find a Journal Article Although the world's first official photovoltaic cell was created by a Frenchman, Alexandre-Edmond Becquerel, in 1839, the concept didn't take hold in the U.S. until Bell Laboratories developed the first solar cell capable of converting solar energy into electricity, in 1954. 17. Pero este sueo de garantizar el acceso universal a la energa elctrica no hubiera sido posible sin Charles Fritts, autor de la primera clula solar slida, la precursora . This endless loop makes it so solar panels can make clean electricity for decades. Please note that if you opt not to accept or if you disable cookies, the Your Finnegan feature on this website will be disabled as well. One major breakthrough came directly from knowledge of Einsteins light quanta (photon) work. Siemens declared to the scientific world that the Americans modules presented to us, for the first time, the direct conversion of the energy of light into electrical energy., Siemens judged photoelectricity to be scientifically of the most far-reaching importance. James Clerk Maxwell agreed. 2020: California requires all new homes to have solar panels. The pioneers in photoelectricity failed to attain the goals they had hoped to reach, but their efforts were not in vain. 1955: The first solar-powered telephone call is made. The story of solar cells goes back to an early observation of the photovoltaic effect in 1839. 1 Physics Ellipse, College Park, MD 20740-3844 | (301) 209-3200, 400 Years of Telescopes, and More, at APS April Meeting, Subscription Revenue, Membership Numbers Hold Steady Despite Downturn, Prize and Award Nominations Now Electronic, APS Video Contest Features Physics of Toys, Solar Energy, Energy Storage Highlight AAAS Symposium, Zero Gravity: The Lighter Side of Science. In 1941, Russell S Ohl at Bell Labs invented the first silicon solar cell, securing US patent no 2,402,662 on his invention. CHARLES FRITTS, THE UNKNOWN INVENTOR OF SOLAR PANELS Solar energy is the second fastest growing renewable energy in the world, according to the International Energy Agency. National Inventors Hall of Fame, Daryl Chapin: Silicon Solar Cell,https://www.invent.org/inductees/daryl-chapin(last visited 23 April 2020). In 1928, Swiss physicist Felix Bloch set out a band theory to explain quantum behavior based on a single crystal periodic lattice.12, In papers published in 1931-1932, British mathematician Sir Alan H Wilson developed a theory explaining how energy bands of electrons determine whether a material is a conductor, semiconductor, or insulator.13In 1948, Gordon Teal and John Little adapted the Czochralski method to produce single-crystalline germanium and silicon.14. Submit a Manuscript 1982: The Sacramento Municipal Utility District commissions its first solar electricity-generating facility. The photon energy absorbed by nanomaterials is transferred to the electrons in the atoms. Click here to read our privacy policy in full. Unfortunately, whether we like it or not, the climate crisis is here, and kids are paying attention to how we react. In materials like selenium, the some photons carry enough energy to knock poorly held electrons from their atomic orbits. In 1873. Einstein, Albert. They demonstrated their solar panel by using it to power a small toy Ferris wheel and a solar powered radio transmitter. This brought the price down from $100 per watt to around $20 per watt. The first solar panel was invented by Charles Fritts in 1883 where he coated a thin layer of selenium with an extremely thin layer of gold. During the experiment Becquerel recognized that a voltage had developed when light struck the electrode. 647-665., doi:10.1016/j.respol.2015.11.001. For example, worldwide solar photovoltaic capacity had grown to 512 Gigawatts by the end of 2018 (representing 27% growth from 2017),18accompanied by a steady decrease in system and installation costs. Many utilities are utilizing solar power during daylight hours. This new legitimacy stimulated further research into photovoltaics and re-vived the dream that the worlds industries could hum along fuel- and pollution-free, powered by the inexhaustible rays of the sun. For his test circuit, he needed a semi-conducting material with a high resistance and selected selenium rods. 1916: Chemist Jan Czochralski invents a method for creating single crystals of metal. Therefore, some consider the true invention of solar panels to be tied . 1954: Bell Laboratories produces the first efficient silicon solar cell. 4. Save time, save money and demystify home solar. Contrasting Mouchots earlier work as directly utilising solar heat to produce steam or hot air, Weston explained that his invention could store solar energy in a chemical battery cell so that energy accumulated during hours of sunshine may be utilised during night or periods of cloudy weather. You may see solar powered cars. 20. A few years later, Charles Fritts of New York moved the technology forward by constructing the worlds first photoelectric module. Una industria que es clave para facilitar la electricidad a 840 millones de personas hoy en da. Albert Einstein shared Minchins suspicions that the science of the age failed to account for all the energy streaming from the sun. How Predictable Is Technological Progress? These novelties were the first items using solar cells that were available to consumers. 19. 1982: The first large-scale solar farm is built near Hesperia, California. The inventors were: Gerald L. Pearson, Daryl M. Chapin, and Calvin S. Fuller (shown at the left). Fritts selenium cells achieved an energy conversion rate of less than 1 percent.4Although others continued to develop and patent photovoltaic cells based on selenium,5it eventually fell out of favor. That of the sun great., Maxwell was among many European scientists intrigued by a behavior of selenium that had first been brought to the attention of the scientific community in an article by Willoughby Smith, published in the 1873 Journal of the Society of Telegraph Engineers. 132-148. The basics of solar energy are part of that discovery, as inventors and scientists lay the groundwork for much of the subsequent history of the technology. The Bell scientists believed that the efficiency figure could be raised to 10 per cent through normal engineering techniques. Wed love to see your vision for the future! In the early 1970s, Dr. Elliot Berman, Chairman and Founder of the Solar Power . His father had a job working as a pay clerk for the British Navy, and the Dickens family, by the standards of the day, should have enjoyed a comfortable life. In 1954, Bell Labs Daryl Chapin, Calvin Fuller, and Gerald Pearson created a silicon single-crystal photovoltaic (PV) cell capable of about 6% conversion efficiency with direct sunlight, enough to power an electric device for several hours of a day.15Their patent, US patent no 2,780,765, issued in 1957. He noticed that in this particular sample, current flowed through this sample when it was exposed to light. Country: United States Birthday: February 27, 1850 Death Date: January 1 , 1903 ( age 52 ) Birth Sign : Pisces About Biography This was obviously not the case when some form of light was applied. Locations and details of historic physics events. Hence, the experimenters concluded, it was clear that a current could be started in the selenium by the action of the light alone. They felt confident that they had discovered something completely new - that light caused a flow of electricity through a solid material. The next major advance in solar cell technology was made in 1940 by Russell Shoemaker Ohl, a semiconductor researcher at Bell Labs. 13. It appears necessary to make our p-n [junction] very next to the surface, Chapin realized, so that the more powerful photons belonging to light of shorter wavelengths could effectively move electrons to where they could be harvested as electricity. Using selenium spread onto a metal plate, Fritts then covered the module with thin gold leaf. The resulting cells had a conversion electrical efficiency of only about 1%. One brave scientist, however, George M. Minchin, a professor of applied mathematics at the Royal Indian Engineering College, complained that rejecting photoelectricity as scientifically unsound an action that originated in the very limited experience of contemporary science and in a so far as we know [perspective ] is nothing short of madness. In fact, Minchin came closest among the handful of nineteenth-century experimentalists to explaining what happens when light strikes a selenium solar cell. A Stoletow, Sur une sorte de courants electriques provoques par les rayons ultraviolets, Comptes Rendus CVI:1149 (1888); A Stoletow,Sur les courants actino-electriques au travers deTair, Comptes Rendus CVI:1593 (1888); A Stoletow, Suite des recherches actino-lectriques, Comptes Rendus CVII:91 (1888); A Stoletow, Sur les phnomnes actino-lectriques, Comptes Rendus CVIII:1241 (1889); AStoletow, - a, 21 J Russian Physico-chem. Even by the 1980s, selenium cells had achieved no more than a 5.0% energy conversion rate.6Fritts applied for but never received a patent on his work. 1929: Physicist Gilbert Lewis coins the term "photons" to describe Einstein's packets of electromagnetic energy. Effect of a copper heater insensible. While solar modules cost $106/watt in 1976 (in 2019 dollars), they drop to just $0.38/watt in 2019, with 89% of that drop happening since 2010. In a few scrawled notes to a friend . The press took notice. Backed by Emperor Napoleon IIIs financial assistance, Mouchot developed a Sun Engine to operate a small, conventional steam engine, and wowed the public by making a block of ice from the suns rays at the Paris World Fair of 1878. Improved designs and advanced materials have made it possible to build solar cells that reach over 40 percent efficiency, and research and development continues with the goal of bringing the cost down and raising the efficiency to make solar power more competitive with fossil fuels. La energa solar es la segunda renovable de mayor crecimiento mundial, segn la Agencia Internacional de la Energa. Digging further, an American inventor named Charles Fritts took credit in making the first solar cell and he is named the first inventor of solar lights. The resulting modules had an electrical conversion efficiency of only 1% due to the properties of selenium. Chapin finally triumphed, reaching his 6 percent goal. Overview and Emissions, Are Portable Solar Panels Worth It? But how do solar panels take sunlight and make it into electricity? 2000: Germany creates a feed-in-tariff program to stimulate the solar industry. There are no suggestions because the search field is empty. Light, he discovered, contains packets of energy, which he called light quanta (now called photons). The great Scottish scientist James Clerk Maxwell wrote in 1874 to a colleague: "I saw conductivity of Selenium as . Einsteins novel description of light combined with the discovery of the electron and the rash of research into its behavior, all happening at the end of the nineteenth century and early twentieth, provided photoelectricity with a scientific framework it had previously lacked. In semiconductor materials, photons can knock electrons from their atomic orbits and, if connected properly by a circuit, could generate enough electricity to do "work". 1962: 3,600 cells from Bell Laboratories power Telstar, the first solar-powered communications satellite. Wanna make a light bulb shine using household items? What does it look like to live in a cleaner environment? Perhaps, Minchin wrote, it simply act[s] as a transformer of the energy it receives from the sun, while its own materials, being the implements used in the process, may be almost wholly unmodified., The scientific community during Minchins time also dismissed photoelectricitys potential as a power source after looking at the results obtained when measuring the suns thermal energy in a glass-covered, black-surfaced device, the ideal absorber of solar heat. Aided by patent protection, this centuries-long technological innovation has steadily improved solar energy conversion efficiency while lowering volume production costs. But way back in 1883, New York inventor Charles Fritts created the first solar cell by coating selenium with a thin layer of gold. By accepting cookies, you agree to our use of cookies. 1958: Vanguard I is the first spacecraft to be powered by solar panels. U.S. Department of Energy. In a daring paper published in 1905, Einstein showed that light possesses an attribute that earlier scientists had not recognized. He was the second son born to James VI of Scotland and Anne of Denmark. 1967: The Soviet Union's Soyuz 1 becomes the rst solar-powered spacecraft to carry humans. Born to two wealthy parents on July 1, 1961, Lady Diana Spencer grew up adjacent to the aristocracy. Its birth accidentally occurred along with that of the silicon transistor, the principal component of every electronic device in use today. Those three pioneers stood on the sometimes-overlooked shoulders of their Bell Labs predecessor Russel Ohl, who discovered how silicon crystals acted as semiconductors when exposed to light. 1887: The Photoelectric Effect Is Observed For example, in 1894 US musician and artist Melvin L Severy secured two patents on optimising the orientation of thermopiles to sunlight. Low-Pressure Sodium Lamp for Street Lights This was in the year 1883, when the solar cell can only reach a 1% efficiency. Serious research into the development of solar technology, based on the invention of monocrystalline silicon solar cells, leaves the laboratory. Pearson, who was aware of Chapins work, went and told his friend not to waste any more time on selenium solar cells, and Chapin immediately switched to silicon. In US patent no. Name: Charles Richard. The first object called a solar panel, made in 1883 by New York inventor Charles Fritts, was made by coating selenium, a mineral found in soil, with gold. Update Contact Information, Librarians "Why the Price of New Solar Electricity Fell an Incredible 89% in the Last Decade." . This timeline highlights some of the major pioneers and events in the emergence of solar technology. Pearson dipped it in lithium, creating a p-n junction. Yes, it says solar energy for kids in the title, but were also hoping you get a moment of reprieve, too. Pearson then hooked up an ammeter to the piece of silicon and shined a light on it. He suggested that the amount of power that light quanta carry varies according to the wavelength of light - the shorter the wavelength, the more power. This groundbreaking achievement laid the foundation for the modern solar power industry and paved the way for the development of renewable energy sources. 1861: Mathematician and physicist Auguste (or Augustin) Mouchout patents a solar-powered motor. By 1975, that figure had dropped to just over $100 a watt. 2008: NREL sets a world record for solar cell efficiency at 40.8%. 2019: The first offshore floating solar farm is installed in the Dutch North Sea. 6, no. H J Hovel and J M Woodall, High efficiency AlGaAs-GaAs solar cells, 21 Appl Phys Lett 379-381 (1972). Today we see solar cells in a wide variety of places. Farmer, J. Doyne and Franois Lafond. Green, Martin A. These rapid responses ruled out the possibility that the heat of the candle flame had produced the current (known as thermal electricity). 1941: Bell Laboratories engineer Russell Ohl files a patent for the first monocrystalline silicon solar cell. 1. F Bloch, ber die Quantenmechanik der Elektronen in Kristallgittern, 52 Zeitschrift fr Physik 555-600 (1928). 1883: Inventor Charles Fritts develops the first solar cell using selenium coated with gold. Its just $1 per month . The current was responsive to not only sunlight, but to dim daylight and even candle light. Lets inject some fun into these conversations about solar energy with some more hands on games and experiments for kids. Figure 2: Severys thermo-pile orientation system in US patent no 527,377. Although we think of solar power as a very modern development overall, Charles Fritts laid much of the groundwork for modern solar cells in 1883. 1977: The Solar Energy Research Institute is established by Congress. Definition, How It Works, and Pros and Cons, The Potential of Solar Paint: Everything You Need to Know, What Is Solar Panel Efficiency? Bell Labs expected it to be useful as a small power source for such applications as rural telephone systems. Proceedings of the Royal Society of London, vol. In 1897, Philadelphia resident Harry C Reagan Jr secured US Patent No 588,177 on a thermo-pile based thermo-battery. We use cookies on this website to provide you with the best user experience. According to Fritts, this early module produced a current "that is continuous, constant, and of considerable force.". The first silicon solar cells were expensive to produce, and early efforts at commercialization were not initially a huge success. In any other climate, the traditional dry-cell battery would do, but in the tropics [it] may have too short a life due to humidity-induced degradation, Chapin explained, and be gone when fully needed. Bell Laboratories had Chapin investigate the feasibility of employing alternative sources of freestanding power, including wind machines, thermoelectric generators, and small steam engines. Across the junction between the two zones there is always a small voltage. Join an APS Unit One problem was the difficulty in making good electrical contacts with the silicon cells. "Forty Years of Photovoltaic Research at UNSW." These massive stone structures were built to withstand attacks Before the widespread use of central heating, churches and other buildings were heated using a variety of methods. King Charles III, the 62nd British monarch to serve over the past 1,200 years, ascended to the throne on September 8, 2022, following the death of his mother, Queen Elizabeth II. April 25, 1954: Bell Labs Demonstrates the First Practical Silicon Solar Cell. A junction means that the crystal is divided into two zones, one containing a slight impurity which produces an excess of movable electrons. Here's how. The first modern solar panels, with a still-meager 4% efficiency, were developed by three researchers at Bell Laboratories, Daryl Chapin, Gerald Pearson, and Calvin Fuller. 124, no. This exponential adoption has been made possible by 180 years of continuing technological innovation in this industry. From an expensive but scientifically sound technology, solar energy benefits from continued government support to become the lowest-cost energy in history. Top. Another problem was that at room temperature, lithium migrated through the silicon over time, moving the p-n junction farther away from the incoming sunlight. But clearly the assumption that all forms of energy of the solar beam are caught up by a blackened surface and transformed into heat is one which may possibly be incorrect, Minchin argued. The US had discovered oil in 1859 and was supplying fuel to meet global energy needs. 1 mil is 1m of an inch, or 25.4 micrometers. Maxwell wondered, Is the radiation the immediate cause or does it act by producing some change in the chemical state? Siemens did not even venture an explanation but urged a thorough investigation to determine upon what the electromotive light-action of [the] selenium depends.. Desert regions even saw solar power bring water where grid power was not an option. Maria Telkes (1900-1995), a Hungarian-American scientist at MIT who worked on several solar energy projects said, Personally, I believe that photovoltaic cells will be the most efficient converters of solar energy if a great deal of research and development work succeeds in improving their characteristics.Top, In April, 1954 a slightly modified wafer of silicon, called a "solar cell", that converted sunlight directly into electrical energy was unveiled by Bell Telephone Laboratories in Murray Hill, NJ. Students. But when the cover of the box was removed, their conductivity the enhancement of electrical flow immediately increased according to the intensity of light., To determine whether it was the suns heat or its light that affected the selenium, Smith conducted a series of experiments. electrical engineer Willoughby Smith's discovery in 1873 that selenium demonstrates this photovoltaic effect, 3 Charles Fritts in 1883 developed and installed the world's first solar panel from selenium cells in New York City. The company soon fails. 527,379. This crack, which had probably formed when the sample was made, actually marked the boundary between regions containing different levels of impurities, so one side was positively doped and the other side negatively doped. Ohl cut a section from the ingot including the top, barrier, and bottom portions, and attached electrodes to the top and bottom portions, yielding the first silicon solar cell, see figure 6. 2,402,662. This selenium module, Fritts reported, produced a current that is continuous, constant, and of considerable force[,]not only by exposure to sunlight, but also to dim diffused daylight, and even to lamplight. As to the usefulness of his invention, Fritts optimistically predicted that we may ere long see the photoelectric plate competing with [coal-fired electrical-generating plants], the first fossil-fueled power plants, which had been built by Thomas Edison only three years before Fritts announced his intentions. The story of the solar cell began in 1839 with French scientist Edmond Becquerels discovery that platinum electrodes coated with silver halides generates electricity when illuminated with blue or ultraviolet light.2Following English electrical engineer Willoughby Smiths discovery in 1873 that selenium demonstrates this photovoltaic effect,3Charles Fritts in 1883 developed and installed the worlds first solar panel from selenium cells in New York City. His research was funded by Exxon Corporation whose off-shore oil rigs needed solar panels to power lights on the top of the rigs to warn oncoming ships. Though she first met Prince Charles at the age of 16, she knew many people in his family: Queen Elizabeth II was her brother's godmother, and she played with Charles's brothers as a child. The history of solar energy is a story of innovation that all started in the early 19th century. When Pearson dipped the rod into a hot lithium bath, according to Fullers formula, the portion of the silicon immersed in the lithium became negatively charged. For example, worldwide solar photovoltaic capacity had grown to 512 Gigawatts by the end of 2018 (representing 27% growth from 2017).1In 1956, solar panels cost roughly $300 per watt. It has less than one percent efficiency in converting solar radiation to electricity. Places Lived: . 18. However, Fritts sent one of his solar panels to Werner von Siemens, whose technical reputation ranked up there with with Thomas Edisons. Early inventions paved the way for the modern silicon cell, most notably by French physicist A. E. Becquerel in 1839 who discovered the photo-electric effect- the birth of the photovoltaic cell. IAM Live: IP and Emerging Technology Europe 2023, Obtaining and Managing REMS Patents: What Patent Prosecutors Need to Know, USPTO and FDA Policies and Rules, Best Practices in Intellectual Property Conference IP in the AI Era: Impact and Challenges, Around the World with Finnegan - Key Developments and Trends in IP Law, 1782 U.S. 2011: Solyndra bankruptcy and investment fiasco slows solar industry growth. On July 29, 1981, Charles married Lady Diana Frances Spencer, daughter of the 8th Earl Spencer. However, solar cells as we know them today are made with silicon, not selenium. While cheaper, these technologies do not provide the high conversion efficiency of single-crystal technologies. Fritts suggested that "we may see the photoelectric plate competing with (coal fired) fossil fuel plants". By During the medieval period, castles were the primary centers of power for feudal lords and monarchs. J Czochralski, Ein neues Verfahren zur Messung der Kristallisationsgeschwindigkeit der Metalle, 92 Zeitschrift fr Physikalische Chemie 219-221 (1918). 1985: Silicon cells that can reach 20% efficiency are created by the Centre for Photovoltaic Engineering at the University of New South Wales in Australia. The solar cell was an outgrowth of transistor research. The needle on their measuring device reacted immediately. International Energy Agency, 2021. Fritts sent one of his solar panels to Werner von Siemens, whose reputation ranked on a par with Edisons. 9. When wires are attached to the selenium bars, the liberated electrons flow through them in the form of electricity. 25, 1876, pp. Chapin soon simplified the process of making silicon solar cells and even developed a solar cell science experiment for high school students. 12, 2015, 1145-1155., doi:10.4236/msa.2015.612113. Solar cell technology has seen exponential growth over the last two decades. Follow, Take a couple of minutes to test your energy knowledge using the, Dig into the science of electricity and create your own. 527,377, Severy arranged thermopiles 1 in a semi-circular frame 25, on a line running east-west, and at an angle that is a mean between the winter and summer declination of the sun. PV system operates with zero carbon-dioxide emissions which has benefits for environmental safety. In the Middle Ages, people primarily used fireplaces or open hearths to warm their homes. However, his contributions to the field were significant, and they paved the way for the development of modern solar power technology. "The History of Solar." Several decades later, in 1873, Willoughby Smith, an English engineer, discovered the photoconductivity of selenium while testing materials for underwater telegraph cables. The world's first rooftop solar array, using Fritts' selenium cells, was installed in 1884 on a New York City rooftop. 2023 C E Fritts, On a new form of selenium cell, and some . Best Known For: Charles Drew was an African American . 2016: Las Vegas, Nevada, becomes the largest city government in America to be run entirely on renewable energy, including from solar panel trees in front of City Hall. Media D C Brock, Useless no more: Gordon K Teal, Germanium, and Single-Crystal Transistors, 24 ChemHeritage Mag 1-2 (2006). Pearson was described by an admiring colleague as the experimentalists experimentalist. Fuller, a chemist, learned how to control the introduction of the impurities necessary to transform silicon from a poor to the preeminent conductor of electricity. The first "real" working solar module was built in 1883 by Charles Edgar Fritts, an American inventor, who constructed modules by coating a wide plate of copper with selenium and then topped it with an extremely thin semi-transparent layer of gold leaf. Smith, the chief electrician (electrical engineer) of the Gutta Percha Company, used selenium bars during the late 1860s in a device for detecting flaws in the transatlantic cable before submersion. Birth date: June 3, 1904. Ohl had inadvertently made a p-n junction, the basis of a solar cell. Before the first modern solar panels were invented by Bell Laboratories in 1954, the history of solar energy was one of fits and starts, driven by individual inventors and scientists. A H Wilson, The Theory of Electronic Semi-Conductors, 133 Proc Roy Soc A 458-491 (1931); A H Wilson, The Theory of Electronic Semi-ConductorsII, 134 Proc Roy Soc A 277-287 (1932). Though the selenium bars worked well at night, they performed dismally when the sun came out. With these incentives, solar panels go from a cost of $1,865/watt in 1956 to $106/watt in 1976 (prices adjusted to 2019 dollars). However, tiny solar cells began to be used in toys and radios. "Solar Cells: In Research and ApplicationsA Review." "NREL Solar Cell Sets World Efficiency Record at 40.8%." To solve that problem, they tried different impurities, and eventually settled on arsenic and boron, which created a p-n junction that stayed near the surface.
