Abstract:
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.
