Abstract
Embodiments provided herein describe methods for forming cadmium-manganese-telluride (CMT), such as for use in photovoltaic devices. A substrate including a material with a zinc blend crystalline structure is provided. CMT is formed above the substrate. During the formation of the CMT, cation-rich processing conditions are maintained. The resulting CMT may be more readily provided with p-type dopants when compared to conventionally-formed CMT.
