photoelectric cell
Light-sensitive detector device
A photoelectric cell is a device that converts light into electrical current.
When light strikes certain materials, it releases electrons, generating a flow of electricity.
Photoelectric cells power solar calculators, operate automatic doors, and form the basis of solar panels.
Also called a photocell or electric eye.
