Charles Fritts (1850–1903) was an American inventor who created the first working selenium cell in 1883, coating selenium with a thin layer of gold to form a semiconductor. Although these cells had low electrical efficiency of about 1%, they were used in early applications like light sensors in cameras and in the first rooftop solar array installed in 1884 in New York City, as noted by CleanTechnica. A photo attributed by Bellingcat shows the cells on George Cove's laboratory roof. Practical solar power advanced with Russell Ohl's development of silicon P/N junction cells in 1941, which improved efficiencies beyond 5%, leading to modern silicon cells reaching over 40% efficiency by 2006 and averaging 21% in 2022.
