摘要：

Photovoltaic effects and photocurrent generation in electrochemical cells consisting of a layer of oriented pigment-polymer complexes sandwiched between two semiconducting electrodes have been investigated. The complexes of chlorophyll a, chlorophyll b and stilbazolium merocyanines with polyvinyl alcohol have been used. The electric and optical properties of the cells have been established. The cells exhibit a potential difference which is changed under illumination. The phenomenon observed is explained supposing the formation of different junctions between the sample and each electrode. This difference is related to an asymmetric distribution of charge across the cell. Surface states related to SnO2 electrode decomposition are formed during aging of the cell.
