Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection and the technical field of backboard composite material preparation, and in particular relates to an environmentally friendly composite material for a solar photovoltaic cell backboard. 【Background technique】 [0002] The solar photovoltaic battery backsheet is located on the back of the solar panel, which protects and supports the battery sheet, and has reliable insulation, water resistance, and aging resistance. Generally has a three-layer structure (PVDF / PET / PVDF), the outer protective layer PVDF has good environmental erosion resistance, the middle layer is PET polyester film with good insulation properties, and the inner layer PVDF and EVA have good bonding properties . At present, the domestic demand for solar cell back film continues to increase, and the market prospect of solar cell back film is very broad. [0003] However, although the existing solar cell back film h...
