Photocell
Transducing components. Ian Sinclair, in Passive Components for Circuit Design, 2001. Photocells. A photocell is a light-to-electrical transducer, and there are many different types available. Light is an electromagnetic radiation of the same kind as radio waves, but with a very much shorter wavelength and hence a much higher frequency.
