Abstract
Official abstract text for this publication.
A multi-junction photovoltaic device includes a germanium layer having pyramidal shapes with (111) facets exposed to form a textured surface. A first p-n junction is formed on or over the textured surface. Another p-n junction is formed over the first p-n junction and following the textured surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-junction photovoltaic device, comprising: a germanium layer having substantially symmetrical pyramidal shapes with (111) facets exposed to form a textured substrate; a first p-n junction formed directly on the textured substrate and following the textured substrate; and at least one other p-n junction formed over the first p-n junction and following the textured substrate. 2. The device as recited in claim 1 , wherein the g…
