HI803 HJT Integrated Encapsulation Film
- HI803 is also designed for high-reliability HJT module encapsulation, helping protect solar cells in damp-heat environments and reducing the risk of hot spots, delamination, and corrosion.
- With >75% crosslinking degree, PCT yellowness index below 3.0, and UV aging ΔYI below 3.0, HI803 is ideal for heterojunction modules requiring long-term stability, aging resistance, and reliable encapsulation.
