GSHK has developed a proprietary process for manufacturing thin-film Copper Indium Gallium diSelenide (CIGS) photovoltaic (PV) modules. Unlike traditional solar panels that are rigid, heavy, and fragile, GSHK Solar thin-film solar modules are lightweight, flexible, and durable. While other companies produce CIGS on glass, Group GS Hong Kong LLC is the only company with CIGS on flexible materials.
CIGS creates more electricity from the same amount of sunlight than do other thin-film PV and therefore has a higher “conversion efficiency”. CIGS conversion efficiency is also very stable over time, meaning its performance continues unabated for many years. The performance of many other PV materials can rapidly decline with use. Customers are well aware that GSHK CIGS does not suffer the degradation in cell efficiency associated with other thin-film PV. (See conclusions of Weizmann Institute as published in Renewable Energy World, September 1999, “CIGS Cells are Self-Repairing”, say researchers).
