Abstract

A method of producing sheets of crystalline material is disclosed which is employed in the construction of tandem solar cells. In the method, a growth mask is formed upon a substrate and crystalline material is grown at areas of substrate exposed through the mask and laterally over the surface of the mask to form a sheet of crystalline material. This sheet is then separated and used to form a tandem solar cell while the substrate can be reused to form additional sheets.
