A device and method for fabricating a photovoltaic device includes forming a double layer transparent conductive oxide on a transparent substrate. The double layer transparent conductive oxide includes forming a doped electrode layer on the substrate, and forming a buffer layer on the doped electrode layer. The buffer layer includes an undoped or p-type doped intrinsic form of a same material as the doped electrode layer. A light-absorbing semiconductor structure includes a p-type semiconductor layer on the buffer layer, an intrinsic layer and an n-type semiconductor layer.
