ETCHING OF CIS/CIGS SOLAR CELLS
We turn solar power into next generation energy. CyPlus manufactures high quality sodium cyanide (NaCN) and potassium cyanide (KCN) suitable for etching CIS/CIGS solar cells.
This process removes excess copper and sulfur from the surface to improve the properties of the semiconductor. CyPlus’s holistic approach makes it possible to use cyanides sustainably.
a) specially designed stainless-steel containers and dissolution systems for transporting and dissolving solid cyanides
(CyPlus® SLS – Solid-to-Liquid System);
b) cyanide monitoring and control equipment to measure and control cyanide concentration (CyPlus® CCS – Cyanide Control System and Oxitrol®) and
c) customized processes to safely treat cyanide-containing effluents in the solar industry (CyPlus® CET – Cyanide Effluent Treatment).
