Abstract

See full text

Improved solar cells are provided by nano-structuring the solar cell active region to provide high optical absorption in a thin structure, thereby simultaneously providing high optical absorption and high carrier collection efficiency. Double-sided nano-structuring is considered, where both surfaces of the active region are nano-structured. In cases where the active region is disposed on a substrate, nano-voids are present between the substrate and the active region, as opposed to the active region being conformally disposed on the substrate. The presence of such nano-voids advantageously increases both optical and electrical confinement in the active region.
