The photovoltaic effect was first observed in 1839 by a young French scientist, Edmond Becquerel, but it would be decades before the process was better understood and fully developed. The key turning point came in the 1870s when scientists discovered that selenium was a semiconductor, and would generate electricity if exposed to sunlight.
The photovoltaic effect is a fundamental phenomenon in the conversion of solar energy into electricity is characterized by the generation of an electric current when two different materials are in contact and exposed to light or electromagnetic radiation.. This effect is mainly activated by sunlight, although it can be triggered by natural or artificial …
6 · In 1839, Alexandre Edmond Becquerel discovered the photovoltaic effect while studying the effect of light on electrolytic cells. Though not equivalent to the photoelectric effect, his work on photovoltaics was instrumental in showing a strong relationship between light and electronic properties of materials.
Initial Development of Solar Power. The development of solar cell technology, or photovoltaic (PV) technology, began during the Industrial Revolution when French physicist Alexandre Edmond Becquerellar first demonstrated the photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity, in 1839.
