Brit.

/ˌfəʊtəʊᵻlɛkˈtrɪsᵻti/,

/ˌfəʊtəʊɛlɛkˈtrɪsᵻti/, U.S.

/ˈˌfoʊdoʊəˌlɛkˈtrɪsədi/,

/ˈˌfoʊdoʊiˌlɛkˈtrɪsədi/; see also electricity n.

Origin: Formed within English, by compounding; perhaps originally modelled on a French lexical item, or perhaps originally modelled on a German lexical item. Etymons: photo- comb. form, electricity n.

Etymology: < photo- comb. form + electricity n., originally after French photo-électricité (1877) or its etymon German Photoelectricität (1877 or earlier; now Photoelektrizität ). Compare earlier photoelectric adj., photoelectrical adj.

Physics.

Electricity produced by the incidence of light; photoelectric properties or phenomena. Also: the branch of physics that deals with these.
