Abstract
A metallic insulative substrate having its surface coated with an insulative layer, on which a large number of photoelectric converter elements are electrically connected to each other in series by connecting the first back electrode layer of one of photoelectric converter elements adjoining each other with the second back electrode layer of the other. Accordingly, electrical connection of these electrode layers in series does not affect the effective area used for photoelectric conversion. This constitution also improves heat resistance of the insulative substrate. Electrical contact of the transparent light-receiving electrode layer) and the second back electrode layer is achieved via contact holes each having a diameter identical to the diameter of those of the insulative and semiconductive layers. As a result, a sufficient insulative distance is provided between the transparent electrode layer and the first back electrode layer so that occurrence of accidental shortcircuit can be securely prevented.
