Premium weatherable backsheets designed for long-term optical reflection and electrical safety.
Protect the back of your modules with our multi-layer PVDF/PET/PVDF (TPT) and PVDF/PET/EVA backsheets. Our films offer superior resistance to hot-spot degradation, moisture ingress, ultraviolet radiation, and sand abrasion. With high inner reflectivity, they help redirect escaping light back into the solar cell, boosting the overall current output.
