    • PROBLEM TO BE SOLVED: To provide a photovoltaic module having a polyvinylidene fluoride back sheet which provides chemical resistance, low water vapor transmission, electrical insulation, and UV light protection even if exposed to the environment.SOLUTION: A photovoltaic module comprises: a) an outer transparent glazing material; b) encapsulated interconnected solar cells; and c) a back sheet comprising a functionalized polyvinylidene fluoride (PVDF) composition, where the polyvinylidene fluoride composition is applied to a back sheet substrate as a solvent or aqueous coating composition. The PVDF composition is selected from a functional PVDF copolymer having 1-29 wt.% of hexafluoropropene, a blend of a non-functional PVDF polymer and a functional or non-functional acrylic polymer with at least 50 wt.% of the blend being PVDF, and an acrylic modified fluoropolymer with the minimum PVDF content of 50%.
    • 要解决的问题:提供一种具有聚偏二氟乙烯背板的光伏模块,其即使暴露于环境中也提供耐化学性,低水蒸气透过性,电绝缘性和UV光保护。解决方案:光伏模块包括:a) 外透明玻璃材料; b)封装的相互连接的太阳能电池; 和c)包含官能化聚偏二氟乙烯(PVDF)组合物的背板,其中所述聚偏氟乙烯组合物作为溶剂或水性涂料组合物施加到背板基材上。 PVDF组合物选自具有1-29重量%六氟丙烯的功能性PVDF共聚物,非功能性PVDF聚合物和功能性或非官能丙烯酸类聚合物的共混物,其中至少50重量%的共混物为PVDF ,和PVDF含量最低为50%的丙烯酸改性含氟聚合物。
