Abstract

A photovoltaic device includes a substrate having a plurality of hole shapes formed therein. The plurality of hole shapes each have a hole opening extending from a first surface and narrowing with depth into the substrate. The plurality of hole shapes form a hole pattern on the first surface, and the hole pattern includes flat areas separating the hole shapes on the first surface. A photovoltaic device stack is formed on the first surface and extends into the hole shapes. Methods are also provided.
