Photoelectric effect invented by
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. In 1873, Willoughby Smith discovered photoconductivity in selenium while testing the met… WebIn the photoelectric effect, light waves (red wavy lines) hitting a metal surface cause electrons to be ejected from the metal.
