The development of solar cell technology, or photovoltaic (PV) technology, began during the Industrial Revolution when French physicist Alexandre Edmond Becquerellar first demonstrated the photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity, in 1839. 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.

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. ANTONIO LPEZ | Tungsteno Charles Fritts' ingenious innovation was the first device to generate electricity by harnessing the power of the Sun, which produces the equivalent of four billion 100-watt light bulbs every second.This energy potential of the Sun had not gone unnoticed throughout history, as the first written records on the use of solar energy date back to the Romans and Greeks, two . 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. Installing solar is also more affordable now due to installation costs dropping over 70 percent in the last decade. You also have the option to opt-out of these cookies. Charles E. Fritz (1921 - 5 May 2000) was an American scientist pioneering disaster research during and following the Second World War . 1891 Baltimore inventor Clarence Kemp patented the first commercial solar water heater. Named after Italian physicist, chemist and pioneer of electricity and power, Alessandro Volta, photovoltaic is the more technical term for turning light energy into electricity, and used interchangeably with the term photoelectric. 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. In 1883, a New York inventor named Charles Fritts lived and worked in a building downtown that would later be replaced by the Federal Reserve Bank. [5] Becquerellars and Einsteins research formed the basis of future developments in solar technology. 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. As a songwriter, Donnie's songs were performed and appeared on the national charts by Charlie Rich (You're Gonna Love . [9] The U.S. government pioneered much of the early PV technology.

[18], The goal of this coordinated federal effort was to make solar viable and affordable and market it to the public. From France to the U.S., inventors were inspired by the patents of the mathematician and filed for patents on solar-powered. Despite vast amounts of subsidies, solar power comprises less than 1 percent of US electricity generation[1] and should no longer be propped up by taxpayer dollars. Bell had funded the research. President Carter labeled the energy crisis as the moral equivalent of war, and made energy policy a top priority of his administration. 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. 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. Feb 27, 1850 Died on 01 Jan 1903 (aged 52) American inventor. In 1883, when New York inventor Charles Fritts created the first solar cell by coating selenium with a thin layer of gold. [22] Opponents of the energy credits in Congress argued that the credits were ineffective and geared toward the wealthy. Essentially, Congress was attempting to turn federal buildings into billboards for solar energy, and it simultaneously passed additional legislation to mobilize several government agencies for research and logistical support to make solar technology affordable.

[2] About four decades later, American inventor Charles Fritts created the worlds first rooftop solar array in New York in 1883, one year after Thomas Edison opened the worlds first commercial coal plant. 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. So, Fritts created what was a low impact solar cell, but still, it was the beginning of photovoltaic solar panel innovation in America. He was 52 years old when he died. Omissions? Fritts's devices were very inefficient converters of energy; they transformed less than 1 percent of absorbed light energy into electrical energy.

In 1897, Reagan was granted U.S. patent 588,177 for an application of solar heat to thermo batteries. In the claims of the patent, Reagan said his invention included a novel construction of apparatus in which the suns rays are utilized for heating thermo-batteries, the object being to concentrate the suns rays to a focus and have one set of junctions of a thermo-battery at the focus of the rays, while suitable cooling devices are applied to the other junctions of said thermo-battery. His invention was a means to collecting, storing and distributing solar heat as needed. The resulting cells had a . [33], In addition to tax credits and grants, the government continues to heavily subsidize the industry with research and development, commercialization, and regulatory support. [13] The act also created a new federal office, The Solar Energy Research Institute, to conduct research and facilitate the industrial use of solar power. The information is used to decide when and how often users will see a certain banner. Declining domestic oil production and rising oil imports throughout the early 2000s helped lead to the passage of the Energy Policy Act of 2005 (EPAct), the first omnibus legislation dealing with energy policy since 1992. Solar cells continued to improve through the 1880s. [3] Fritts coated the panels with selenium to produce a very weak electric current. 1904 - Wilhelm Hallwachs makes a semiconduc tor .

As a technology that has been around for well over a century, solar power is neither novel nor new. Naval Research Laboratory launched Vanguard I, the first spacecraft to use solar panels, in 1958,[8] and NASA launched the first satellite equipped with panels that tracked the Sun, Nimbus I, in 1964. 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.
