In photovoltaic modules, there is a gap between the crystalline silicon cells, and the light passing through the gap cannot be used directly to generate electricity. By applying a light-guiding film to the backsheet in the gap area, light can be redirected and captured by the cells. This additional light can increase the power output of the module. TPK's newly developed product enhances the all-day power gain through an ultra-dispersive, highly reflective inorganic coating that is compatible with PET. Performance Characteristics: Enhancement of oblique light reflectivity and increase of total power gain throughout the day - Highly insulating material to build rough surface; - Ultra-matte, diffuse reflection; - Ultra-high reflectivity at all angles Ultra High Weather Resistance - Non-metallic material, super weather resistant; - Cross-linked EVA Ultra-thin products - Reduces film thickness by 21% and improves lamination yields; Insulation material - No leakage hazard Intellectual Property - No hidden dangers
