摘要
The present invention provides a method and precursor structure to form a Group IBIIIAIVA solar cell absorber layer. The method includes forming a Group IBIIIAVIA compound layer on a base by forming a precursor layer on the base through electrodepositing three different films, and then reacting the precursor layer with selenium to form the Group IBIIIAVIA compound layer on the base. The three films, described by the precursor layer, include in one embodiment a first alloy film comprising copper, indium and gallium, a second alloy film comprising copper and selenium formed on the first alloy film; and a selenium film formed on the second alloy film.
