Alexandre-Edmond Becquerel (French pronunciation: [alɛksɑ̃dʁ ɛdmɔ̃ bɛkʁɛl]; 24 March 1820 – 11 May 1891), [1] known as Edmond Becquerel, was a French physicist who studied the solar spectrum, magnetism, electricity and optics.He is credited with the discovery of the photovoltaic effect, the operating principle of the solar cell, in 1839. [2] [3] He is also known for his work in
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.
The photovoltaic effect occurs in solar cells. These solar cells are composed of two different types of semiconductors - a p-type and an n-type - that are joined together to create a p-n junction. To read the background on what these semiconductors are and what the junction is, click here.
French physicist Edmond Becquerel discovered the photovoltaic effect, which is the creation of voltage or electric current in a material upon exposure to light. 1880s: American inventor Charles Fritts created the first solar cell using selenium coated with a thin layer of gold.
