Among them, the structural reinforcement layer is mostly a PET film. The film has good comprehensive performance, is resistant to stretching, has strong weather resistance and good insulation. Therefore, an anti-static, temperature-resistant and wave-transparent battery backplane is proposed here.

According to the mass ratio of the A-layer polyester film to the B-layer polyester film of 400-900:100, they are respectively melted by an extruder at 260°C - 290°C, and then co-extruded layer by layer through a resin melt distributor, cast on a cold drum at 15°C - 25°C, and then longitudinally stretched 2.9 - 3.5 times and transversely stretched 3.0 - 3.5 times, and heat-set at 190°C - 230°C to obtain a high partial discharge voltage solar cell backplane base film with a thickness of 100μm - 350μm; the partial discharge voltage of the high partial discharge voltage solar cell backplane base film of the present invention is 800V - 1800V; the partial discharge voltage and long-term ultraviolet resistance and other properties are good; it is suitable for the manufacture of solar photovoltaic cell backplane materials. After studying the above patent and the prior art, it is found that the wave-transparent effect of the existing battery backplane is not good. Therefore, the utility model proposes an anti-static, temperature-resistant and wave-transparent battery backplane again. Summary of the Utility Model
