Photovoltaics

Willoughby Smith discovered the photovoltaic effect in selenium in 1873. In 1876, with his student Richard E. Day, William G. Adams discovered that illuminating a junction between selenium and platinum also has a photovoltaic effect. These two discoveries formed a foundation for the first selenium solar cell construction, which was built in 1877.

Photovoltaic Effect

Becquerel (a French physicist) discovered the photoelectrochemical (photovoltaic) effect in 1839 [32], while he was investigating the effect of light on metal electrodes immersed in electrolytes. Since this discovery, technology evolved to allow the production of materials with many types and structures presently used in photovoltaic technology.
