THE PHOTOSENSITIVITY AND PHOTOCURRENT KINETICS OF ZINC OXIDE-POLYMER BINDER LAYERS HAVE BEEN INVESTIGATED AS A FUNCTIONOF POLYMER CONCENTRATION, INTENSITY OF INCIDENT LIGHT AND APPLIED FIELD IN THE SURFACE CELL CONFIGURATION. IT WAS FOUNDTHAT THE PHOTOSENSITIVITY AT A CERTAIN POLYMER CONCENTRATION WAS REMARKABLY HIGHER THAN THAT FOR PURE ZINC OXIDE. THE GROWTH AND DECAY RATES OF THE PHOTOCURRENT WERE ALSO FOUND TOBE HIGHLY DEPENDENT ON THE POLYMER CONCENTRATION. THE I-V CHARACTERISTICS FOR THESE PHOTORECEPTORS REVEALED A HIGHLY NON-OHMIC NATURE OF CONDUCTION MECHANISM. THESE OBSERVATIONS HAVE BEEN EXPLAINED ON THE BASIS OF A MODEL BASED ON THE BARRIER LAYER THEORY FOR THE PHOTOCONDUCTIVITY.
