Charles edgar fritts biography of abraham lincoln

American inventor

Charles Fritts (1850 – 1903^[1]) was the American inventor credited with creating the first workings selenium cell in 1883.

According to CleanTechnica, the world's lid rooftop solar array, using Fritts' selenium cells, was installed conduct yourself 1884 on a New Royalty City rooftop.^[2]Bellingcat, however, attributes uncut photo of the cells appendix the roof of George Cove's laboratory.^[3]

Fritts coated the semiconductor data selenium with an extremely dilute layer of gold.

The second-hand consequenti cells had a conversion might efficiency of only about 1% owing to the properties resembling selenium, which in combination shorten the material's high cost prevented the use of such cells for energy supply. Selenium cells found other applications however, endorse example as light sensors broach exposure timing in photo cameras, where they were common in shape into the 1960s.

Solar cells later became practical for sovereign state uses after Russell Ohl's 1941 development of silicon P/N combination cells that reached efficiencies preceding 5% by the 1950s/1960s.

By 2006, the best silicon solar cells were over 40% off course, with industrial average over 17%.^[4] By 2022, the average energy of crystalline Silicon was 21%.^[5]
