Betterial, a China-based developer of solar module materials, is set to exhibit its BC product range at SNEC 2025. According to Betterial, the Ultra-Transparent EVA/EPE Film has increased average light transmittance by over 0.2% across the 380 to 1100 nm spectrum. The company has reported that its infrared high-reflective encapsulants have achieved up to 95% reflectivity, improving photoelectric conversion by 2% to 4% per 100 W module. Betterial has developed Ultra-Barrier Film with anti-hydrolysis and ion adsorption technologies to prevent EVA resin aging and contact corrosion. Westdon insulating adhesives, available in thermal and UV-curing types, are designed to improve rear electrode insulation with strong adhesion and fast curing. Betterial has confirmed that all materials are compatible with TOPCon, HJT, Tandem Perovskite, and Perovskite cells to meet next-generation module performance and reliability requirements.
