A safer, easier and more effective method for removal of copper sulfide impurities in thin film solar cell materials such as Copper Zinc Tin Sulfide (CZTS) and Copper Indium Gallium Selenide ( CIGS).
Primary Application Area: Materials, Chemical
Technology Development Status: Prototype
FIGURES OF MERIT
Value Proposition: • More effective than currently used methods for removal of impurities from thin film solar cell materials
• Uses less toxic and easier to handle solvents
• Potentially less expensive than current methods
Companies who manufacture thin film solar cell materials specifically Copper Zinc Tin Sulfide (CZTS) and Copper Indium Gallium Selenide (CIGS) would be interested in this technology. Both CZTS and CIGS are emerging solar cell technologies but are not yet commercialized. CIGS is closer to market than CZTS.
