Of or relating to the electric effects caused by light. pho′to·e·lec′tri·cal·ly adv.photoelectric (ˌfəʊtəʊɪˈlɛktrɪk) or photoelectricaladj (General Physics) of or concerned with electric or electronic effects caused by light or other electromagnetic radiation ˌphotoeˈlectrically adv photoelectricity npho•to•e•lec•tric (ˌfoʊ toʊ ɪˈlɛk trɪk) also pho`to•e•lec′tri•cal, adj. of or pertaining to electronic effects produced by light, esp. the phenomenon whereby a surface emits electrons when exposed to light. [1860–65] pho`to•e•lec•tric′i•ty (-ɪ lɛkˈtrɪs ɪ ti, -ˌi lɛk-) n. pho·to·e·lec·tric (fō′tō-ĭ-lĕk′trĭk) Relating to the electrical effects of light. For example, exposure to light can bring about the emission of electrons from a material, the generation of an electric current, or a change in the electrical resistance of a material. ♦ The emission of electrons from a material, such as a metal, as a result of being struck by photons (light) is called the photoelectric effect.ThesaurusAdj. | 1. | photoelectric - of or pertaining to photoelectricity; "the photoelectric effect"photoelectrical | Translationsphotoélectriquefotoelettrico
photoelectric
photoelectric, photoelectrical of or concerned with electric or electronic effects caused by light or other electromagnetic radiation photoelectric[¦fōd·ō·i′lek·trik] (electronics) Pertaining to the electrical effects of light, such as the emission of electrons, generation of voltage, or a change in resistance when exposed to light. photoelectricConverting photons into electrons. When light is beamed onto a metal, electrons are released from its atoms. The higher the light frequency, the more electron energy released. Photonic sensors of all kinds work on this principle. They sense light and cause an electric current to flow.
Although most people think Einstein won the Nobel Prize because of his Theory of Relativity, it was actually due to his discovery of the photoelectric effect. He theorized that light was made of particles (later called photons) and that it carried an amount of energy exactly proportional to its frequency. See phototransistor and photovoltaic.photoelectric
