The present disclosure is directed to methods of forming different types of CuZnSnS(CZTS) solar cells and Copper Indium Gallium DiSelenide (CIGS) solar cells that can be combinatorially varied and evaluated. These methodologies all incorporate the formation of site-isolated regions using a combinatorial processing tool and the use of these site-isolated regions to form the solar cell area. Therefore, multiple solar cells may be rapidly formed on a single substrate for use in combinatorial methodologies. Any of the individual processes of the methods described may be varied combinatorially to test varied process conditions or materials.

Combinatorial methods for making CIGS solar cells

Methods for developing and investigating materials and processes for various layers used in manufacturing CdTe, CIGS, and CZTS TFPV superstrate devices using high productivity combinatorial techniques is described. Typical layers subjected to the HPC techniques include the buffer layers, absorber layers, and the contact interface layers.
