Thin-Film Photovoltaics

P9300 series is a photovoltaic packaging material prepared by EVA/POE/EVA and POE co-extrusion with a specific formula, which can effectively bond glass, backplane and other materials for a long time to protect and fix solar cells. It has excellent electrical insulation performance, excellent weather resistance (including high temperature resistance, high humidity, UV, etc.), excellent adhesion performance retention rate after aging, better light transmittance, to ensure the power generation efficiency of the component, low shrinkage rate, to ensure the lamination quality stability, can effectively prevent the risk of PID components.
