photoelectricity
Radiance releasing electrons
Photoelectricity is the generation of electrical current or voltage when light strikes certain materials.
The phenomenon underlies solar cells, light meters, and digital camera sensors.
Einstein's explanation of the photoelectric effect—that light behaves as discrete packets of energy—earned him the Nobel Prize and helped establish quantum physics.
