Abstract

A photovoltaic device is presented. The photovoltaic device includes a transparent conductive layer; a window layer disposed on the transparent conductive layer; and an absorber layer disposed on the window layer. The window layer includes a low-diffusivity layer disposed adjacent to the transparent conductive layer and a high-diffusivity layer interposed between the low-diffusivity layer and the absorber layer. Method of making a photovoltaic device is also presented.
