Abstract
A three-dimensional structure having a mixture of inverted pyramidal cavities and substantially flat areas defines the frontside and backside of a substrate. The substantially flat areas have ridges forming base openings of the inverted pyramidal cavities and planar linear regions across the substrate. Pyramidal sidewalls define the pyramidal cavities from the ridges to pyramidal apices. Metallization contacts emitter regions on the frontside of the substantially flat areas.
