Webphotocell in British English. (ˈfəʊtəʊˌsɛl ) noun. a device in which the photoelectric or photovoltaic effect or photoconductivity is used to produce a current or voltage when exposed to light or other electromagnetic radiation. They are used in exposure meters, burglar alarms, etc. Also called: photoelectric cell, electric eye. WebConfusion reigns over photocells and solar cells, but there is an easy way to tell them apart. A solar cell produces power for an electrical circuit while a photocell is a light-activated control switch. Photocells have been used since the mid 1900s in light meters while solar cells have only become popular since 1990.
