A method for forming a photovoltaic device includes depositing a p-type layer on a substrate. A barrier layer is formed on the p-type layer by exposing the p-type layer to an oxidizing agent. An intrinsic layer is formed on the barrier layer, and an n-type layer is formed on the intrinsic layer.

Methods for forming a photovoltaic device include depositing a p-type layer on a substrate and cleaning the p-type layer by exposing a surface of the p-type layer to a plasma treatment to react with contaminants. An intrinsic layer is formed on the p-type layer, and an n-type layer is formed on the intrinsic layer.
