photocell

/fˈoʊɾoʊsˌɛl/ noun

A photoelectric cell.

Word Origin Photocell combines photo- 'light' and cell 'small room', so it's a 'light-cell' — a device that converts light into electricity. Cell comes from Latin cella 'small room', originally a storeroom, from PIE *kel- 'to cover, conceal'. The same root gives us cellar, conceal, and occult. So a photocell is literally a tiny room for light.
