Abstract:
A photovoltaic device includes a substrate layer having a plurality of three-dimensional structures formed therein providing a textured profile. A first electrode is formed over the substrate layer and extends over the three-dimensional structures including non-planar surfaces. The first electrode has a thickness configured to maintain the textured profile, and the first electrode includes a transparent conductive material having a dopant metal activated within the transparent conductive material. A continuous photovoltaic stack is conformally formed over the first electrode, and a second electrode is formed on the photovoltaic stack.
