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, … See more When a photoconductive material is connected as part of a circuit, it functions as a resistor whose resistance depends on the light intensity. In this context, the material is called a photoresistor (also called light … See more Some materials exhibit deterioration in photoconductivity upon exposure to illumination. One prominent example is hydrogenated amorphous silicon (a-Si:H) in which a metastable reduction in photoconductivity is observable (see Staebler–Wronski effect See more The characterization technique called photoconductivity spectroscopy (also known as photocurrent spectroscopy) is widely used in studying optoelectronic properties of semiconductors. See more Sensitization is an important engineering procedure to amplify the response of photoconductive materials. The photoconductive gain is proportional to the lifetime of photo-excited carriers (either electrons or holes). Sensitization involves intentional … See more In 2016 it was demonstrated that in some photoconductive material a magnetic order can exist. One prominent example is CH3NH3(Mn:Pb)I3. In this material a light induced magnetization melting was also demonstrated thus could be used in magneto optical … See more • Photodiode • Photoresistor (LDR) • Photocurrent See more WebPhotoconductors are used for X-Ray image detectors; These are used for relay control; These are used to switch on & off transistors.

WebJul 11, 2024 · Photoconductors. The operating principle of the photoconductors is based on photoconductive effect, that is, the conductivity of the materials changes under illumination. The photoconductors without p-n junction always need an external electric field to separate the photogenerated carriers from electron-hole pairs.
