ABSTRACT:
A method of making group I-III-VI compound semiconductors such as copper indium diselenide for use in thin film heterojunction photovoltaic devices. A composite film of copper, indium, and possibly other group IIIA elements, is deposited upon a substrate. A separate film of selenium is deposited on the composite film. The substrate is then heated in a chamber in the presence of a gas containing hydrogen to form the compound semiconductor material.
