Abstract:
A method of manufacturing a photoelectric transducer for obtaining photoelectromotive force on a conductive substrate having an electrically conductive surface, comprising the steps of:transferring the conductive substrate to immerse a part of the conductive substrate in a cleaning liquid containing water, and applying an ultrasonic wave to the cleaning liquid, thereby conducting ultrasonic cleaning;contacting the surface of the substrate with purified water after the ultrasonic cleaning and before drying of the substrate, the contact with the purified water being effected by spraying the purified water onto the substrate, said transferring step and said contacting step being performed in such manner as to impart to the surface a uniform oxidation; anddrying the conductive substrate contacted with the purified water, then forming on the surface of the substrate an electrically conductive film and then a semiconductive layer.
