PHOTOELECTRIC PROPERTIES OF ORGANIC SEMICONDUCTOR MATERIALS

The work is devoted to the study of the mechanism of charge photogeneration in low dimensional and polymer organic materials by the photoinduced discharge method. It is shown that in the investigated materials the process of the charge photogeneration is the multistep process, the final step, thermal dissociation of light generated electron-hole pairs, can be well described by the Onsager model. It is found that the photogeneration quantum yield in all investigated materials is the function of temperature and the electric field.
