Abstract:
1. A method of making a photovoltaic (PV) cell, said method comprising the steps of: (a) providing a first component comprising a cadmium telluride (CdTe) layer comprising an interfacial region; (b) subjecting the first component to a functionalizing treatment to obtain a first green component, said functionalizing treatment comprising treating at least a portion of the interfacial region with a first material comprising copper and a second material comprising chlorine; (c) subjecting the first green component to a first annealing treatment to obtain a second green component; (d) subjecting the second green component to a processing treatment; and (e) disposing a second component adjacent the CdTe layer to form the PV cell.
