Abstract
A method of making a photo-electric converting element which includes the steps of forming a photoconductive layer on an insulative substrate by applying a single substance of Group II-VI compound semiconductors which include Cd, or two or more Group II-VI compound powders; and then baking to form a photoconductive layer having a thickness of 1 to 10 .mu.m and a surface roughness of 0.2 to 1 .mu.m and also having its peripheral edge tapered outwardly with respect to the substrate at an angle not greater than 60.degree. and forming a counterelectrode by the use of a lift-off technique so as to overlay a portion of the photoconductive layer.
