WebJan 9, 2024 · Responsivity and photoconductivity gain are two essential parameters in the discussion of photoconductivity. The term photoresponsivity indicates the photocurrent generated per unit of excitation power. 46 The value of photoresponsivity is obtained by multiplying the photoconductance by the square of the electrode spacing and dividing by … 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 In 2016 it was demonstrated that in some photoconductive material a magnetic order can exist.
