the effect observed when electromagnetic radiation, esp visible light from the sun, falls on a thin film of one solid deposited on the surface of a dissimilar solid producing a difference in potential between the two materials
photovoltaic effect in American English
noun
Physics
the phenomenon in which the incidence of light or other electromagnetic radiation upon the junction of two dissimilar materials, as a metal and a semiconductor, induces the generation of an electromotive force
Word origin
[1955–60]This word is first recorded in the period 1955–60. Other words that entered Englishat around the same time include: backgrounder, cassette, geodesic dome, new wave, software
