The first solar cell was created in by Russell Ohl, a materials scientist at Bell Labs. Its energy conversion efficiency was 1%, so for every 100 Joules of solar energy that fell upon it, it created 1 Joule of electrical energy. [1] Over the past 70 years, silicon solar cells have been pushing towards the maximum limit of 32% for silicon ...

Dec 27, · History of Diode: In the year at Bell Labs, Russell Ohl was working with a silicon crystal to find out its properties. One day accidentally when the silicon crystal which has a crack in it was exposed to the sunlight, he found the flow of current through the crystal and that was later called as diode, which was the beginning of the semiconductor era.
