Axuntek Solar Energy is using DuPont PV5400 series ionomer encapsulant in its IEC-certified CIGS thin-film modules, the company has announced.
The solar modules are frameless and the first to adopt DuPont PV5400 into CIGS technology. The modules aid to reduce shipping costs because they permit a higher density in shipping, therefore lower costs. Further, the modules are stronger due to DuPont’s encapsulant. The combination of ionomer and glass allows for the utilization of the frameless modules in building-integrated applications.
Penny Perry, global marketing manager, DuPont PV Encapsulants, commented: “The use of the DuPont PV5400 series ionomer encapsulants in CIGS modules demonstrates multiple benefits of the ionomer encapsulant’s inherent qualities. It provides strength to enable a frameless design, transparency for more design flexibility and ensures more power output over the life of the module.”
“The performance level of the PV5400 encapsulant was a key factor in these frameless solar modules receiving IEC certification,” said Ray Lin, sales and marketing manager for Axuntek. “CIGS technology offers the potential to reach higher efficiencies than other thin film technologies, and the choice of encapsulant is important to ensure the highest level of performance and long-term durability. DuPont PV5400 not only increases the modules’ durability and production efficiency, but can significantly enhance their long-term power-generating efficiency.”
