  Provided is a vinylidene fluoride resin composition resistant to yellowing in the test for evaluation of durability of moist heat resistance, even when it is laminated directly on an ethylene vinyl acetate copolymer (EVA)-based sealing material, and a resin film, a back sheet for solar cells and a solar cell module comprising the same. A vinylidene fluoride resin composition at least comprising a vinylidene fluoride resin having a peak value ratio of head-to-tail bond to head-to-head bond (head-to-tail bond /head-to-head bond), as determined by 1H-NMR, of 11.5 or less and a mass-average molecular weight (Mw) of 1.30×105 or more, and an antioxidant is processed into a vinylidene fluoride resin film having a thickness of 10 to 200 µm. The vinylidene fluoride resin film and an electric insulating resin film such as polyethylene terephthalate-based film are laminated, to give a back sheet for solar cells.

  本发明提供了一种在湿热耐久性评价试验中即使直接层压在以乙烯-醋酸乙烯共聚物（EVA）为基材的密封材料上也不会变黄的偏氟乙烯树脂组合物，以及由其构成的树脂薄膜、太阳能电池背板和太阳能电池组件。 将至少包含一种偏氟乙烯树脂的偏氟乙烯树脂组合物加工成厚度为 10 至 200 微米的偏氟乙烯树脂薄膜，该偏氟乙烯树脂组合物通过 1H-NMR 测定的头尾键与头顶键的峰值比（头尾键/头顶键）为 11.5 或以下，质量平均分子量（Mw）为 1.30×105 或以上，并包含一种抗氧化剂。将偏氟乙烯树脂薄膜和电绝缘树脂薄膜（如聚对苯二甲酸乙二醇酯薄膜）层压，制成太阳能电池背板。
