The back sheet of the solar cell is an indispensable part of the solar cell. The back sheet is the protective material on the back of the solar cell, used to support and fix the solar cell, and has the ability to continuously resist light exposure. The backplane is required to have good resistance to environmental erosion, insulation and good adhesion to EVA. As an important part of photovoltaic modules, the backsheet material is the main packaging material. The backing material must have very low thermal resistance, and must prevent the entry of water or water vapor, protect and support the battery, and have reliable insulation, water resistance, and aging resistance. The outermost layer of the backplane can resist environmental corrosion, the middle layer should have good insulation properties, and the inner layer should have good adhesion to EVA. The backplane is mainly used to resist damage to the components caused by the harsh environment and ensure the service life of the components.
