Description

一种太阳能电池背板及其制备方法 技术领域
本发明涉及一种太阳能电池背板及其制备方法。 背景技术
作为传统电能生产方法的绿色替代方案， 光伏电池组件被用来利用太 阳光产生电能。 光伏电池组件是由各种半导体元件系统组装而成， 因而必 须加以保护以减轻环境作用如湿气、 氧气和紫外线的影响和破坏。 光伏电 池组件通常采用的是在硅片两侧层压贴附玻璃或塑料膜保护层的结构。 由 于具有优良的强度、 耐候性、 抗紫外性和阻湿性能， 用氟聚合物薄膜和聚 酯（PET )薄膜层叠而成的背板在光伏电池组件中发挥着重要作用。 传统的 背板生产方式是将预先制造好的氟聚合物薄膜特别是聚氟乙烯（ PVF )薄膜 粘贴于聚酯 （PET )基材上， 典型的是在 PET 两侧贴附氟聚合物薄膜而形 成 "三明治" 结构。 当氟聚合物薄膜（如 PVF )用作光伏电池组件背板时， 它的性能明显地改善了组件的使用寿命， 使组件保证使用寿命达到 25年。
然而， 若要预生产的氟聚合物薄膜与聚合物基底材料间紧密粘附， 且 暴露在户外若干年后也不会脱开是很难实现的。 此前采用的技术措施， 如 美国专利 US3133854、 US5139878和 US6632518都描述了通过在贴附氟聚 合物薄膜之前在基材上预涂底层或粘接层以得到耐久的层叠结构背板的方 法。 然而， 这些方法都需要在真正的层叠步骤之前提供至少一个粘接层或 底层和粘接层， 然后在层叠步骤通过受热和压力作用完成层叠， 因此， 使 用预生产的氟聚合物薄膜层叠的方法步骤繁多， 成本较高。 同时， 由于预 生产的氟聚合物薄膜必须有足够的厚度以满足在贴合及后处理程序过程中 对其强度的要求， 使得膜的实际厚度比为提供保护性能所需的厚度大， 造 成价格昂贵的氟树脂薄膜的浪费， 提高了产品的成本。 发明内容
本发明所要解决的技术问题是提供一种太阳能电池背板， 该背板不需 要使用附加的底层或粘合剂层， 其生产成本低， 性能优良。
本发明要解决的另一技术问题是提供一种太阳能电池背板的制备方 法， 该方法工艺简单， 可以实现连续工业化生产。
为解决上述技术问题， 本发明所采用的技术方案是：
本发明提供一种太阳能电池背板， 包括基材和含氟聚合物层， 所述含 氟聚合物层的组分及其重量份数为：
含氟树脂 25 ~ 45份；
改性树脂 1.5 3份；
聚合物填料 0.5 - 3份；
无机填料 0.1 ~ 1份；
溶剂 50 - 70份。
上述太阳能电池背板， 所述含氟树脂是偏氟乙烯、 四氟乙烯、 六氟丙 烯的均聚物或它们的共聚物。
上述太阳能电池背板， 所述改性树脂是用羧酸基、 磺酸基、 氮杂环丙 烷基、 异氰酸酯基、 环氧基、 胺基、 羟基或活性亚曱基改性处理的聚偏氟 乙烯一四氟乙烯一六氟丙烯树脂。
上述太阳能电池背板， 所述含氟聚合物层包括选自如下元素的氧化物 的无机填料： 钛、 铝、 锡或硅。
上述太阳能电池背板， 所述溶剂是甲笨、 丁酮、 醋酸乙酯、 醋酸丁酯 中的一种或几种。
上述太阳能电池背板， 所述含氟聚合物层的厚度为 25 ~ 50 μ ιη。
此外， 本发明还提供一种制备本发明所提供的上述太阳能电池背板的 方法： 即， 在基材表面上涂布含氟聚合物层， 固化得到太阳能电池背板。 一般用于太阳能电池背板的基材是聚酯， 例如， 它可以是聚对笨二曱 酸乙二酯（PET )、 聚萘二曱酸乙二酯 PEN或它们的双层共挤的产物。 根据 用途不同， 基材可以是透明、 白色或黑色。
为了能够更好的体现出含氟聚合物的特性例如耐候性、 耐溶剂性和阻 隔性， 用于本发明的含氟树脂可以是偏氟乙烯、 四氟乙浠、 六氟丙烯的均 聚物或它们的共聚物， 优选下列含氟树脂：
聚偏氟乙烯树脂；
聚偏氟乙烯-四氟乙烯树脂；
聚偏氟乙烯-六氟丙烯树脂；

表中：
1. 水蒸气透过率测试：
使用 Mocon Permatron-W 700设备， 依据标准 ATSM 1249进行测试。
2. 耐候性测试：
使用 Q-Sun Xe-3-H型氙灯耐候老化试验箱，依据标准 ISO 4892-2进行 测试。
3. 涂层附着力测试
依据标准 ASTM 3359进行测试。
使用百格刀划格器在涂层上切出十字格子图形， 切口直至底材， 这样 可以得到由 100个小方格组成的被测单元。 使用 3M公司的 PSA467胶带，使胶带长度方向与其中一个划痕平行的 紧密的贴附在测试区域表面上， 用力压实， 然后将胶带从和涂层面为 0度 角的方向迅速的用力撕开， 观察涂层面的变化， 任何面积的涂层脱落均判 定为剥离强度不合格。
从表中数据可以看出， 与传统方式制造的背板对比样品相比， 本发明 提供的含氟聚合物薄膜完全能够满足作为光伏组件产品背板的需要。
