WebThe photoelectric effect is the emission of electrons or other free carriers when light shines on a material. Electrons emitted in this way can be called photo electrons. This phenomenon is generally studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry.
