Abstract

Thin-film solar cells have already reached grid parity with conventional fossil fuel energy sources, and slightly undercut traditional crystalline silicon solar cells, however they still have the potential to lower their levelized cost further. Currently, commercial thin film solar cells are still relatively expensive due to rare elemental constituents, high energy intermediate processing & fabrication methods, and scalability limitations. Cu2ZnSnSxSe(4-x) (CZTSSe) has exemplary semiconductor properties for solar energy harvesting; with earth abundant & non-toxic elements, ideal direct bandgap, and potential solution processability, which would significantly lower costs. The commercial viabi..
