Profile: Edmond Becquerel

Edmond Becquerel was a participant or observer in the following events:

French scientist Edmond Becquerel, 19 years old, discovers the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes placed in an electricity-conducting solution. Becquerel’s experiment proves that heightened amounts of electricity can be generated when the cell is exposed to sunlight. He coins the term “photovoltaic effect” to describe his finding. Basically, the photovoltaic effect (PV) occurs when the energy from photons strikes a semiconducting material such as silicon or platinun, and transfers its energy to an atom of the semiconducting material. The energized electron then escapes its bond and generates an electric current. The “gap” created by the escaped electron works with the electron to create the current.
