Photoconducting Properties of Film Composites Based on Polyvinyl Butyral and Heterometallic Cu/Mo Complexes

摘要

We have synthesized and studied novel photosensitive polymer film composites based on non-photoconducting polyvinyl butyral doped with heterometallic Cu/Mo complexes. We have established that these composites have photoconducting and photovoltaic properties and are characterized by hole-type photoconductivity. The photocurrent and the photo-EMF are higher for composites in which complexes are used that have a shorter distance between nearest-neighbor metallic copper centers, which is explained by better conditions for transport of nonequilibrium holes.
