Summary:A photovoltaic device and method include a substrate layer having a plurality of structures including peaks and troughs formed therein. A continuous photovoltaic stack is conformally formed over the substrate layer and extends over the peaks and troughs. The photovoltaic stack has a thickness of less than one micron and is configured to transduce incident radiation into current flow.
