Abstract
The results of the research on the photovoltaic effect in a planar system formed from the following layers: ITO, CdTe, zinc perfulorophthalocyanine, bathocuproine and Ag (ITO/CdTe/F 16ZnPc/BCP/Ag) are presented. The system exhibited strong current rectification in the dark. A photogeneration of charge carriers in the CdTe layer and at the CdTe/F 16ZnPc junction was observed under illumination. The short-circuit current and open-circuit voltage versus light intensity can be explained as a result of a trap-assisted recombination process operating within the heterojunction. The current is limited by space charge for higher values of forward bias.
