    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： Methods are provided for forming a back contact for a photovoltaic cell that includes at least one semiconductor layer. One method includes depositing at least one back contact material on a metal contact. The back contact material comprises a metal nitride or a metal phosphide. The method further includes depositing an absorber layer comprising cadmium and tellurium above the back contact material and thermally processing the back contact material, such that the back contact material interacts with the absorber layer to form an interlayer that lowers a contact resistance for the photovoltaic cell. A photovoltaic cell is also provided and includes comprising a metal contact, at least one back contact material disposed on the metal contact, and an absorber layer comprising a material comprising cadmium and tellurium disposed above the back contact material. An interlayer is disposed between the back contact material and the absorber layer and comprises a compositionally graded layer of the back contact material and the absorber layer material. The photovoltaic cell further includes a window layer disposed above the absorber layer.
