THIN FILM STACKS FOR GROUP V DOPING, PHOTOVOLTAIC DEVICES INCLUDING THE SAME, AND METHODS FOR FORMING PHOTOVOLTAIC DEVICES WITH THIN FILM STACKS

Abstract:

According to the embodiments provided herein, a method for forming a photovoltaic device can include depositing a plurality of semiconductor layers. The plurality of semiconductor layers can include a doped layer that is doped with a group V dopant. The doped layer can include cadmium selenide or cadmium telluride. The method can include annealing the plurality of semiconductor layers to form an absorber layer.
