The invention discloses an adhesive film with different UV absorption wavebands and a preparation method thereof. The adhesive film with different UV absorption wavebands is prepared from the following components in parts by weight: 100 parts of matrix resin, 0.1 to 2 parts of peroxide cross-linking agent, 0.1 to 2 parts of assistant cross-linking agent, 0.05 to 2 parts of UV absorption aid, 0.05 to 2 parts of UV light conversion agent, 0.1 to 2 parts of silane coupling agent, 0 to 1 part of light stabilizer and 0 to 1 part of antioxidant. The adhesive film with different UV absorption wavebands can selectively block UV light wavebands, block wavebands damaging a battery piece and keep non-destructive wavebands to pass through, so that the power of a battery piece assembly is improved. 本发明公开了一种不同UV吸收波段的胶膜及其制备方法。该发明的不同UV吸收波段的胶膜，按重量份计，包括如下组分：基体树脂100份、过氧化物交联剂0.1-2份、助交联剂0.1-2份、UV吸收助剂0.05-2份、UV光转换剂0.05-2份、硅烷偶联剂0.1-2份、光稳定剂0-1份、抗氧剂0-1份。本发明的不同UV吸收波段的胶膜，可以选择性阻隔UV光波段，阻隔对电池片有损害的波段，保留无损害的波段穿过，提高了电池片组件的功率。
