Photoconductive polymers absorb electromagnetic radiation and produce an increase of electrical conductivity. Photoconductive polymers have been used in a wide variety of technical applications such as Xerography (electrophotography) and laser printing. Electrical conductivity is usually very small in organic compounds. Conductive polymers usually have large electrical conductivity. Photoconductive polymer is a smart material based on conductive polymer, and the electrical conductivity can be controlled by the amount of radiation.
The basic parameters of photoconductivity are the quantum efficiency of carrier generation(), the carrier mobility(), electric field(E), temperature(T), and concentration(C) of charge carriers. The intrinsic properties of photoconductive polymers are the quantum efficiency () and carrier mobility(), which will determine the photocurrent. Photocurrent will be affected by these four kinds of processes: charge-carrier generation, charge injection, charge trapping, charge carrier transport.
Hundreds of photoconductive polymers have been disclosed in patents and literature.[1] There are mainly two types of photoconductive polymer: negative photoconductive polymers and magnetic photoconductive polymers.
