Charles Fritts ( – [1]) was the American inventor credited with creating the first functional selenium cell in
According to CleanTechnica, the world's first rooftop solar array, using Fritts' selenium cells, was installed in on a New York City rooftop.[2]Bellingcat, however, attributes a photo of the cells to the roof of George Cove's laboratory.[3]
Fritts coated the semiconductor material selenium with an extremely thin layer of gold.
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 employ of such cells for force supply. Selenium cells found other applications however, for example as light sensors for exposure timing in photo cameras, where they were common well into the s.
The Surprising History of Solar Panels: A Kid’s Instruction to ...: Charles Fritts ( – [1]) was the American inventor credited with creating the first working selenium cell in According to CleanTechnica, the world's first rooftop solar array, using Fritts' selenium cells, was installed in on a New York City rooftop. [2].Solar cells later became practical for force uses after Russell Ohl's growth of silicon P/N junction cells that reached efficiencies above 5% by the s/s.
By , the best silicon solar cells were over 40% efficient, with industrial average over 17%.[4] By , the average efficiency of crystalline Silicon was 21%.[5]
