charles fritts biography

Inventors have been advancing solar technology for more than a century and a half, and improvements in efficiency and aesthetics keep on coming, Elizabeth Chu and D. Lawrence Tarazano, U.S. Patent and Trademark Office. 1883 - Charles Fritts develops a solar cell using selenium on a thin layer of gold to form a device giving less than 1% efficiency . Charles Fritts, an American inventor, described the first solar cells made from selenium wafers. However, the process of how light produces electricity wasnt understood until Albert Einstein wrote a paper explaining the photoelectric effect in 1905,[4] which won him the Nobel Prize in physics in 1921. 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. [7] The U.S. Copyright Solar Edition 2020, All Content is Shareable with Solar Edition Reference. 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 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. It was around this time in the 1970s that an energy crisis emerged in the United States. [16] President Carter signed the Department of Energy (DOE) Organization Act in 1977, and the agency was activated on October 1 of that year. 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. Bellis, Mary. The Government Accountability Office found that there were at least 345 solar-related initiatives supported by six government agencies in 2011 and 2012.[34].

Any device that directly converts the energy in light into electrical energy through the process of photovoltaics is a solar cell. 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. 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. 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.

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. The thermal battery was invented to collect and store heat by having a large mass that can heat up and release energy. [23] In 1979, Representative Bill Frenzel remarked: The principal tax credit bill we passed last year does not seem to have given great incentive in the marketplace The tax credit does not motivate, but rather simply occurs at the end of the year when the fellow finds there was a tax credit available.

Theyve been an eyesore for neighbors at times, and surely a pain for homeowners associations to deal with, but the benefits to the environment are substantial. 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. In 1954, three American researchers, Gerald Pearson, Calvin Fuller, and Daryl Chapin, designed a silicon solar cell capable of a six percent energy conversion efficiency with direct sunlight. As a technology that has been around for well over a century, solar power is neither novel nor new.
