Industry Friendly Solution Synthesis and Processing Earth Abundant Cu2ZnSn(SSe)4 Solar Cells


Kesterite copper zinc tin chalcogenide Cu2ZnSnS4 (CZTS) is a promising candidate material for large-scale low-cost solar energy enterprises. CZTS has optical and electronic properties comparable with CIGS material systems and is not burdened by the scarcity and cost issues associated with other semiconducting solar materials. UCLA researchers have developed a process to fabricate CZTS thin films using industry friendly solvents thereby minimizing use of the highly reactive and hazardous hydrazine solvents that are employed in current production lines. The researchers have further optimized the deposition and annealing steps of kesterite CZTS thin film production using the industry friendly solvents.


Low Cost less hazardous.
