Photoconductivity - an overview | ScienceDirect Topics
Photoconductivity is the increase in electrical conductivity of a material that takes place when the material is illuminated with infrared, visible, or ultraviolet light. The absorption of light is a quantum process in which electrons are excited to higher energy levels. Ordinarily, the excited electrons are more mobile than unexcited electrons.
