The mixed composite of TiO2 and CdO were prepared by heat treatment technique taking firing temperature 700 ËšC for 30 min. Five samples having different compositions were prepared. 100% TiO2 sample heated at 700 ËšC for 30 minutes was found to be best photosensitive. However (80% TiO2 - 20% CdO) samples shows maximum photosensitivity amongst all other compositions. For measurement purpose the thick binder layer were fabricated in the form of parallel plate capacitor. The response time of 100% TiO2 and (80% TiO2 - 20%CdO) samples are 36sec and 25 second respectively. Rise and decay of photocurrent under different experimental conditions such as under ultra violet radiations, different voltages and different light intensities have been studied.
