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.

Integrated three-dimensional and planar metallization structure for thin film solar cells

A structure and method operable to create a reusable template for detachable thin semiconductor substrates is provided. The reusable template has a three-dimensional (3-D) surface topography comprising a plurality of raised areas comprising a rounded top and separated by a plurality of depressed areas.

Structure and method for creating a reusable template for detachable thin film substrates

A structure and method operable to create a reusable template for detachable thin semiconductor substrates is provided. The template has a shape such that the 3-D shape is substantially retained after each substrate release. Prior art reusable templates may have a tendency to change shape after each subsequent reuse; the present disclosure aims to address this and other deficiencies from the prior art, therefore increasing the reuse life of the template.
