Betterial showcased a TPO film designed for low-temperature processing of perovskite modules
Its film for BC modules uses an ultra-low-flow formulation designed to reduce silver-paste consumption
The company offers HC806 light-conversion film for application-specific scenarios
Chinese encapsulation material supplier Betterial presented application-specific encapsulation solutions for perovskite, back-contact (BC), and TOPCon modules at SNEC 2026. The company also showcased its HC806 light-conversion film for modules deployed in high-UV environments.
For perovskite modules, Betterial presented a thermoplastic (TPO) encapsulation film designed for low-temperature lamination. According to the company, its halogen-free formulation helps avoid the risk of chemical corrosion of the perovskite layer caused by halide residues generated by conventional crosslinked films. Betterial says the film enables low-temperature lamination while maintaining strong adhesion between the module layers. The company offers 2 modules for perovskite modules: the B606L high-transmittance film and the B606LP UV-cutoff film. Both offer light transmittance of at least 85% between 380 nm and 1,100 nm and adhesion to glass of at least 80 N/cm. B606L has UV transmittance of at least 75%, while B606LP limits UV transmittance to 10% or less.
For BC modules, Betterial offers an encapsulation film using an ultra-low-flow formulation. The film is designed to resist damp-heat aging, yellowing, and potential-induced degradation (PID). According to the company, it also supports lower silver paste consumption.
Betterial also showcased a high-transmittance encapsulation solution for TOPCon modules. According to the company, the film improves light transmission and photon utilization and is designed to resist UV exposure and long-term aging.
Along with the solutions for advanced technology, the company also presented encapsulation film for application-specific scenarios. For modules used in deserts, plateaus, and other high-UV environments, Betterial presented its HC806 light-conversion film. The film converts UV light into visible light with more than 95% efficiency. Betterial claims a module power gain of 1.2% to 3%. The company also reports less than 3% degradation after UV60 aging and says the film helps mitigate ultraviolet-induced degradation (UVID) and PID-related performance losses.
