NOVELTY - A high fluoro-mixcrystal coated solar photovoltaic cell backplane comprises structure of seven layers arranged sequentially from top to bottom, including first base layer, first high fluoro-mixcrystal coating (2), second base layer (3), polyethylene terephthalate layer (4), third base layer (5), second high fluoro-mixcrystal coating (6) and fourth base layer. The first high fluoro-mixcrystal coating is applied between lower surface of first base layer and upper surface of second base layer. The second high fluoro-mixcrystal coating is applied between third base layer and fourth base layer.    USE - High fluoro-mixcrystal coated solar photovoltaic cell backplane.    ADVANTAGE - The photovoltaic cell backplane has improved coating hardness, thus exhibiting good scratch resistance. When wiping off silicon sealant from surface, the coating surface of backplane may not be damaged, thus quality of backplane is ensured, and service life of assembly is prolonged, which can be over 25 years.    DETAILED DESCRIPTION - High fluoro-mixcrystal coated solar photovoltaic cell backplane comprises structure of seven layers arranged sequentially from top to bottom, including first base layer, first high fluoro-mixcrystal coating (2), second base layer (3), polyethylene terephthalate (PET) layer (4), third base layer (5), second high fluoro-mixcrystal coating (6) and fourth base layer. The first high fluoro-mixcrystal coating is applied between lower surface of first base layer and upper surface of second base layer. The second high fluoro-mixcrystal coating is applied between lower surface of third base layer and upper surface of fourth base layer. The PET layer is applied between lower surface of second base layer and upper surface of third base layer. The high-hardness nanopowder (0.1-1 wt.%) is added to each of first high fluoro-mixcrystal coating and second high fluoro-mixcrystal coating; and based on the overall weight of the high fluoro-mixcrystal coatings.
