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]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.

In fact, President Jimmy Carter had 32 solar panels installed on the roof of the White House in Only a few years later in , inventor Edward Weston received two patents for solar cells — U.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. 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.
Solar cells later became practical for power uses after Russell Ohl's development 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]

As we continue to seek sustainable energy solutions, it's essential to acknowledge and celebrate the visionaries like Charles Fritts who dared to imagine a future powered by the sun.
