RenewSys Launches POE Encapsulant Tailormade for n-type TOPCon

RenewSys named its product-- CONSERV E – NT.

Indian Solar Module Manufacturer RenewSys claimed to introduce India’s first POE (Polyolefin Elastomer) Encapsulant specifically formulated for N-type TOPCon PV cells. The firm has named it CONSERV E – NT. The renewable company said that the product will help in reducing the degradation of the n-type TOPCon solar cells.

“The solar PV market is constantly evolving, driven by the need to maximize efficiency while extending the lifespan of solar PV modules. N-type TOPCon Modules are the natural successor to Mono PERC and Multi technologies, offering higher efficiencies and a longer operating life. However, N-type TOPCon cells are far more susceptible to environmental damage; thus, there is a significant need to safeguard them. This necessity has driven our Innovation team to formulate an Encapsulant that protects N-type TOPCon cells, ensuring unmatched output and durability,” RenewSys said in a media statement.

The firm said that RenewSys’ newly designed 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 module components.

The green energy firm said that CONSERV E-NT extends multiple key advantages to module manufacturers, reducing rejection rates and boosting production efficiency.

“CONSERV E – NT offers several notable benefits to module manufacturers. It 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,” it said.

It also said that it is compatible with laminators with both one-side and two-side heating. “Another significant advantage of CONSERV E – NT is evident in Glass-Glass TOPCon PV modules, where its use renders the modules bubble-free. The encapsulant also effectively restricts string shifting, a long-standing challenge in module production. These factors further contribute to reducing module rejection rates, ensuring a streamlined and efficient manufacturing process,” it added.

RenewSys said that CONSERV E – NT POE Encapsulant is versatile and suits both Glass-Glass and Glass-Backsheet N-type TOPCon solar modules.

Mr Avinash Hiranandani, Vice Chairman and Managing Director of RenewSys, said, “This innovation reinforces our position as a leading Indian manufacturer with a strong global reach. We are known for introducing commercially effective products in the highly competitive solar polymer market.”
