Photoinduced charge carrier generation and trapping in an organic material, viz., Michler’s ketone (tetramethyldiaminodiphenyl ketone), in the form of a binder layer, has been studied. The material forms fairly good photoelectrets, stored charge being of the order of 10−9Coul. Photoelectret charge shows saturation effects for different polarizing parameters, viz., time of photopolarization, intensity of illumination, and applied voltage. An exponentially rising photoinduced voltage has been observed which persists even in the dark, i.e., the material forms an autophotoelectret state as well.
