Abstract
In particular embodiments, a method is described for depositing thin films, such as those used in forming a photovoltaic cell or device. In a particular embodiment, the method includes providing a substrate suitable for use in a photovoltaic device and plasma spraying one or more layers over the substrate, the grain size of the grains in each of the one or more layers being at least approximately two times greater than the thickness of the respective layer.
