Abstract
A photoelectric transducer comprising at least a light-transmissive substrate having a relatively flat surface provided on its light-receiving side and an uneven surface provided on its opposite side, and a photoelectric transducing layer provided on the uneven surface of the substrate. The photoelectric transducing layer comprises at least a light-transmissive conductive layer, a semiconductor layer, and a back conductive electrode layer. The back conductive electrode layer comprises a second light-transmissive conductive layer and a conductive layer. The uneven surface on the substrate includes numerous projections, each projection having a triangular section and a shape of pyramidal, ridged roof, or conical type. The projections and the second light-transmissive conductive layer of the uneven back conductive electrode layer elongate the optical path of light beams in the photoelectric transducing layer, and prevent the adherence of dust particles and the abrasion of the photoelectric transducing layer.
