[14] The overall goal of the agency was to commercialize solar energy. So, Fritts created what was a low impact solar cell, but still, it was the beginning of photovoltaic solar panel innovation in America. The Energy Research and Development Administration (ERDA), another organization created by the 1974 bills, was responsible for delivering comprehensive reports on the development of the agencys solar program to the highest levels in government, including the president and congressional leadership. 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. [10] This energy crisis catalyzed the federal governments commitment to develop solar energy. Selenium cells found other applications however, for example as light sensors for exposure timing in photo cameras, where they were common well into the 1960s.

The resulting cells had a conversion electrical efficiency of only about 1% owing to the properties of selenium, which in combination with the material's high cost prevented the use of such cells for energy supply. Solar cells continued to improve through the 1880s. Although this patent was not for a solar panel, these thermal generators were invented to either convert heat directly into electricity or to transform that energy into power for heating and cooling. For both patents, Weston proposed, to transform radiant energy derived from the sun into electrical energy, or through electrical energy into mechanical energy. Light energy is focused via a lens (f) onto the solar cell (a), a thermopile (an electronic device that converts thermal energy into electrical energy) composed of bars of dissimilar metals. The light heats up the solar cell and causes electrons to be released and current to flow. Germanium Properties, History and Applications, An Atomic Description of Silicon: The Silicon Molecule, A Brief History of White House Solar Panels, Henri Becquerel and the Serendipitous Discovery of Radioactivity. By 2006, the best silicon solar cells were over 40% efficient, with industrial average over 17%. The thermos piles, or solar cells as we call them today, were mounted on a standard to allow them to be controlled in the vertical direction as well as on a turntable, which enabled them to move in a horizontal plane.

Severys second patent from 1889 was also meant for using the suns thermal energy to produce electricity for heat, light and power. In 1941, Russell S Ohl at Bell Labs invented the first silicon solar cell, securing US patent no 2,402,662 on his invention. By 2006, the best silicon solar cells were over 40% efficient, with industrial average over 17%. Only a few years later in 1888, inventor Edward Weston received two patents for solar cells U.S. Patent 389,124 and U.S. Patent 389,425. About 50 years later, Charles Fritts constructed the first true solar cells using junctions formed by coating the semiconductor selenium with an ultrathin, nearly transparent layer of gold. Nevertheless, the government has given vast sums of money to the solar industry since the 1970s, and the stream of special interest handouts has only accelerated in recent years. She is known for her independent films and documentaries, including one about Alexander Graham Bell. Updated: November 9, 2011 . Omissions? The resulting cells had a . ). Our editors will review what youve submitted and determine whether to revise the article. President Carter even tried to generate interest among Americans by installing solar panels on the White House in 1979. Today, companies are striving towards better looking and advanced solar technology, such as. Solar energys story began with Edmond Becquerels work, a young physicist working in France, who in 1839 observed and discovered the photovoltaic effect a process that produces a voltage or electric current when exposed to light or radiant energy. Thus, through the Energy Tax Act of 1978, Congress created the commercial investment tax credit (ITC) and the residential energy credit (or residential ITC) to provide financial incentives for the public to purchase solar properties. [15], The creation of new energy policies continued throughout the 1970s. Congress passed five energy bills in 1974, two of which cited solar power as a potential solution to the energy crisis. It all began with Edmond Becquerel, a young physicist working in France, who in 1839 observed and discovered the photovoltaic effect a process that produces a voltage or electric current when exposed to light or radiant energy. Solar cells later became practical for power uses after Russell Ohl"s 1941 development of silicon p/n junction cells that reached efficiencies above 5% by the 1950s/1960s. Updated: November 9, 2011 [31], The American Recovery and Reinvestment Act of 2009, also known as the federal stimulus, extended massive new subsidies to the solar industry. Una industria que es clave para facilitar la electricidad a 840 millones de personas hoy en da. According to Encyclopedia Britannica, the first genuine solar cell was built around 1883 by Charles Fritts, who used junctions formed by coating selenium (a semiconductor) with an extremely thin layer of gold. The Government Accountability Office found that there were at least 345 solar-related initiatives supported by six government agencies in 2011 and 2012.[34]. Biography ID: 74810405 . The modern photovoltaic (PV) cell was developed by Bell Labs in 1954[6] and while solar power remained too costly for commercial use, the U.S. military funded research on PV technologys potential to power satellites in the 1950s. That same year, a Russian scientist by the name of Aleksandr Stoletov created the first solar cell based on the photoelectric effect, which is when light falls on a material and electrons are released.
