Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A photovoltaic device, comprising: a substrate having a plurality of hole shapes formed therein, the plurality of hole shapes each having a hole opening extending from a first surface and narrowing with depth into the substrate, the plurality of hole shapes forming a hole pattern on the first surface, the hole pattern including flat areas separating the hole shapes on the first surface, wherein each of the hole openings has a pitch relative to adjacent hole…
