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.
