[foh-toh-i-lek-trik] /ˌfoʊ toʊ ɪˈlɛk trɪk/
pertaining to the electronic or other effects produced by light.
of or concerned with electric or electronic effects caused by light or other electromagnetic radiation
photoelectric pho·to·e·lec·tric (fō’tō-ĭ-lěk’trĭk) or pho·to·e·lec·tri·cal (-trĭ-kəl)
Of or relating to the electric effects, especially increased conductivity, caused by light.
Relating to or exhibiting to electrical effects upon exposure to light. For example, some photoelectric materials emit electrons called photoelectrons upon exposure to certain frequencies of light; others, such as photoresistors and phototransistors, change their electrical properties. See also photoelectric effect.
noun, Electronics. 1. . noun 1. another name for photocell photoelectric cell An electronic device having an electrical output that varies in response to the strength of incident electromagnetic radiation, especially visible light. Photoelectric cells make use of the photoelectric effect, in which electrons are displaced by photons in substances such as silicon or selenium […]
noun, Physics. 1. .
noun, Physics. 1. the phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface. noun 1. the ejection of electrons from a solid by an incident beam of sufficiently energetic electromagnetic radiation 2. any phenomenon involving electricity and […]
