| Abstract: | This review briefly described a few accessible technique of surface photovoltage spectroscope (SPS) and their working principles. Based on prototype examples, it outlined the application of SPS technique in investigating the photoelectric structure of organic semiconductors, in the relationship between the optical-electronic properties and thin film fabrication methods, and in researching the heterojunctions formed by different semiconductors. A novel phenomenon of photovoltaic polarity inversion (PVPI) found in studying the photoconductive property of titania phthalocyanine (TiOPc)/chloridian blue (DBCL) composites was introduced. We also point out the prospect on the promising application of SPS in studying the optoelectronic properties of organic semiconductors. |
