    摘要: A method for forming a back contact for a photovoltaic cell that includes at least one semiconductor layer is provided. The method includes applying a continuous film of a chemically active material on a surface of the semiconductor layer and activating the chemically active material such that the activated material etches the surface of the semiconductor layer. The method further includes removing the continuous film of the activated material from the photovoltaic cell and depositing a metal contact layer on the etched surface of the semiconductor layer.

    摘要: Embodiments of the present invention include a method. The method includes producing a first vapor from a solid source material, reacting hydrogen telluride to form a second vapor comprising tellurium, and depositing on a support a coating material comprising tellurium within a deposition environment, the deposition environment comprising the first vapor and the second vapor. Another embodiment is a system. The system includes a deposition chamber disposed to contain a deposition environment in fluid communication with a support; a solid source material disposed in fluid communication with the deposition chamber; and a hydrogen telluride source in fluid communication in fluid communication with the deposition chamber.
