A Short History of Solar Panels
The production and usage of industrial solar energy has been in practice from the past 100 years. In earlier days, solar energy was used to produce steam, which helps to run machinery. But, it was not continued till Henri Becquerel discovered photovoltaic effect, which could convert commercial solar power energy into electrical energy. This discovery of photovoltaic cells by Henri led to the discovery of first genuine solar cell in the year 1893 by Charles Fritts. The initial solar cell was coated with selenium sheets covered with a thin layer of gold.
An American inventor, Russel Ohl in Bell laboratories patented for the silicon cells in 1941. This invention by Ohl led to the development of solar cell in 1954. These cells were first used in the satellites to supply power to it. Probably, the first solar panel was used in a calculator in 1970s. Today these serve as main source of energy.
