Abstract

The optical properties of ZnPc–CdS composite thin films have been measured. The composite layers were prepared by vacuum evaporation. The electrical conduction mechanism prevailing in these junctions was of Poole–Frenkel type and the activation energy was found to have a linear dependence with applied field. The maximum photoconductivity occurred at an energy gap around 1.5 to 1.7 eV. The photosensitivity is found to increase with increase in applied voltage.
