In this study the photocapacitive behavior of organic semiconductor, photosensitive material copper phthalocyanine (CuPc) were investigated. Thin film of the copper phthalocyanine was deposited by vacuum evaporation on glass substrate with silver surface-type electrodes and Ag/CuPc/Ag photo capacitive sensor was fabricated. It was shown that under filament lamp illumination up to 1000 lx the capacitance of the Ag/ CuPc/Ag photo capacitive sensor increased continuously up to 20% with respect of dark condition. It is assumed that photo capacitive response of the sensor is associated with polarization due to the transfer of photo-generated electrons and holes.
