When were solar cells invented?
The first solar cell, by Charles Fritts, was invented in 1883, but this was the very first one. This incredibly early solar cell had conversion efficiencies of under 1%. In 1941 and 1954, there were 2 more improvements to the solar cell, the latter being capable of 6% conversion efficiency with direct sunlight.
