Photo emissive cell types
WebA photo-emissive cell is a type of gas-filled or vaccum tube that is sensitive to light. It makes use of photo electric effects, the phenomenon whereby light sensitive surface give off electrons when stuck by light. when photons strike the cathod the electrons in the ligh-sensitive substance absorb the energy.
