Problems solved by technology

[0004] Fluoroolefin-ethylene multi-polymer (FEVE) has the characteristics of high fluorine content, which is more suitable as the substrate of solar cell back sheet coating, but its impact resistance is poor, and the outer coating of solar cell back sheet is directly connected with photovoltaic modules and The external environment is exposed to factors such as branches and leaves, sand and gravel, strong wind erosion, etc., and its material properties determine the photoelectric conversion performance of photovoltaic modules to a certain extent.
