RenewSys launches encapsulant for n-type TOPCon solar PV Cells

RenewSys says its Conserv E–NT POE (polyolefin elastomer) encapsulant is specially designed to prevent the degradation of n-type TOPCon solar modules in field operations. The encapsulant suits both glass-glass and glass-backsheet TOPCon panels.

RenewSys has introduced India’s first POE (polyolefin elastomer) encapsulant specifically designed for n-type TOPCon PV cells.

The manufacturer said its encapsulant, Conserv E–NT, contains a free radical scavenger that effectively shields TOPCon cells from irreversible damage caused by free radicals generated during the day-to-day PV module functioning. Some common causes of these attacks include fluctuating temperatures, high heat, water ingress, and chemicals from other components of the module.

Conserv E-NT features a wider lamination processing window, allowing for a larger range of acceptable operating conditions during lamination. This directly translates to increased throughput and higher productivity in module manufacturing plants by minimizing module rejections due to lamination issues.

Conserv E-NT is compatible with both one-side and two-side heat laminators. Its use in glass-glass TOPCon PV modules renders the modules bubble-free. The encapsulant also effectively restricts string shifting, a long-standing challenge in module production. These factors further contribute to a reduction in module rejection rates, ensuring a streamlined and efficient manufacturing process, stated RenewSys.

Conserv E-NT suits both glass-glass and glass-backsheet n-type TOPCon solar modules.

Avinash Hiranandani, vice chairman and managing director, RenewSys, said, “This encapsulant will help manufacturers reap many rewards as more and more Indian Module manufacturers introduce their TOPCon offerings. It also ensures that deterioration of TOPCon modules in the field during day-to-day operations is prevented, providing confidence to end customers—homes and businesses adopting solar power.”

Headquartered in Mumbai, RenewSys is an integrated PV module manufacturer with 2.5 GW of panel production capacity, 6 GW of encapsulants, 4 GW of backsheets, and 130 MW of PV cells. It has produced and supplied over 22 GW of encapsulants and backsheets worldwide.

RenewSys is the ‘renewable energy’ arm of the Enpee Group, an international conglomerate established in 1961.
