(Summary description)Plasma cleaning equipment low-temperature plasma treatment of the surface performance of the fluorine-containing coating on the solar backplane: Photovoltaic power generation is a hot topic at the moment, especially the concept of distributed photovoltaics, which further makes photovoltaic power generation a clean energy that residents can afford. The use environment of solar panels is harsh, so the performance of solar backplanes is very important. As the protective layer of solar cells, the solar back sheet must have excellent weather resistance, high insulation, low water permeability and good adhesion performance. There are currently two main types of solar backplanes: 1: Coated back sheet, using fluorine-containing resin coated on the surface of the substrate PET polyester film; 2: Glue-coated composite back sheet, using a layer of fluorine film on the surface of the base material polyethylene terephthalate (PET) film. In actual use, it can be freely combined according to the use environment, performance requirements, price and other factors. Fluorine-containing material has good weather resistance, but it also has high water and oil repellency, which is not conducive to bonding with solar encapsulation film EVA. Plasma cleaning equipment low-temperature plasma treatment of the surface of fluorine-containing materials, improve the bonding performance of fluorine-containing materials and solar packaging film ethylene-vinyl acetate copolymer (EVA), and provide stable and effective protection for solar cells. The electrons in the low-temperature plasma of the plasma cleaning equipment obtain energy from the electric field and become free high-energy electrons. They collide with atoms and molecules in the gas to produce excitation and ionization phenomena, and the excited molecules, atoms, ions and free radicals generated thereby are all The extremely unstable ones have high chemical reactivity and are prone to some reactions to generate new compounds. When the fluorocarbon coatings are processed, the surface layer can be etched to form new properties, or cause cross-linking and polymerization. Under the same processing speed, the processing power of the plasma cleaning equipment plasma processor increases, the contact angle decreases, and the surface tension increases. After reaching a certain power, the surface tension and contact angle tend to be stable. The peeling force between the backsheet and EVA is also consistent with the changes exhibited by the changes in surface tension, and tends to be stable. After low-temperature plasma treatment, the surface energy of the fluorine-containing coating increases, the contact angle decreases, and the peeling force of EVA increases, thereby improving its adhesion to EVA. With the increase of plasma cleaning equipment's low-temperature plasma processing power and time, it is conducive to the improvement of its surface performance.
