feb 8, 1955 - Solar Cell

Description:

English electrical engineer Willoughby Smith discovered the photoconductivity of selenium, meaning it becomes electrically conductive when it absorbs light. Three years later, William Grylls Adams and Richard Evans Day learned that selenium could produce electricity from light without heat or moving parts that could easily break down. This discovery proved that solar power was easy to harvest and maintain, requiring fewer parts than other energy sources — such as coal-fired plants.https://www.solarpowerauthority.com/a-history-of-solar-cells/
