Photovoltaic junctions formed on silk-screened cadmium-sulphide layers

Methods for making cadmium-sulphide photovoltaic junctions which are based on polycrystalline semiconductor layers of cadmium sulphide deposited by a silk-screening technique have been developed, and some experimental results on their electrical characteristics are reported. The methods employed in the preparation of these junctions avoid the difficulties involved in producing large-area CdS solar cells by evaporation in vacuum.
