1. photoconductivity

   Photoconductivity is the phenomenon in which a material's electrical conductivity increases when it is exposed to light. This occurs due to the absorption of photons, which excite electrons from the valence band to the conduction band, creating free charge carriers. The more light the material absorbs, the more free charge carriers are generated, thus increasing the material's electrical conductivity. This property is utilized in various applications including photodetectors, solar cells, and optical communications.

1. Photoconductivity

   Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation. When light is absorbed by a material such as a semiconductor, the number of free electrons and electron holes increases and raises its electrical conductivity. To cause excitation, the light that strikes the semiconductor must have enough energy to raise electrons across the band gap, or to excite the impurities within the band gap. When a bias voltage and a load resistor are used in series with the semiconductor, a voltage drop across the load resistors can be measured when the change in electrical conductivity of the material varies the current flowing through the circuit. Classic examples of photoconductive materials include the conductive polymer polyvinylcarbazole, used extensively in photocopying; lead sulfide, used in infrared detection applications, such as the U.S. Sidewinder and Russian Atoll heat-seeking missiles; and selenium, employed in early television and xerography.
