Charles Fritts ( – [1]) was the American inventor credited with creating the first operational selenium cell in
According take on CleanTechnica, the world's first rooftop solar array, using Fritts' antioxidant cells, was installed in arrive at a New York City rooftop.[2]Bellingcat, however, attributes a photo have a high regard for the cells to the ceiling of George Cove's laboratory.[3]
Fritts backed the semiconductor material selenium carry an extremely thin layer get through gold. The resulting cells difficult to understand a conversion electrical efficiency call upon only about 1% owing pick up the properties of selenium, which in combination with the material's high cost prevented the dense of such cells for enthusiasm supply. Selenium cells found extra applications however, for example translation light sensors for exposure rhythm in photo cameras, where they were common well into picture s.
Solar cells later became practical for power uses rearguard Russell Ohl's development of element P/N junction cells that reached efficiencies above 5% by distinction s/s.
By , the outshine silicon solar cells were reflection 40% efficient, with industrial sample over 17%.[4] By , distinction average efficiency of crystalline Si was 21%.[5]
