Abstract

A photovoltaic device includes a p-type layer. An intrinsic layer is formed directly on the p-type layer and includes an interface region extending into the intrinsic layer that includes a gradually decreasing band gap energy going from the p-type layer into the intrinsic layer formed by a graded deposition temperature. An n-type layer is formed directly on the intrinsic layer.
