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，预生产的氟哦聚合物薄膜与聚合物基底材料间紧密粘附，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：
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

一般用于太阳能电池背板的基材是聚酯，例如，它可以是聚对苯二甲酸乙二酯(PET)、聚萘二甲酸乙二酯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、四氟乙烯、六氟乙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；

适合本发明的溶剂可以是甲苯、丁酮、醋酸乙酯、醋酸丁酯中的一种或几种。
在本发明的含氟聚合物薄膜中，先制备含氟聚合物层的涂布液，该涂布液含有以上所列的含氟树脂，改性树脂，聚合物填料，无机填料，并通过溶剂将组合物粘度调整到适宜涂布的范围。含氟聚合物层的组分及其重量份数为：

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
本发明提供的太阳能电池背板，可以通过下述方法制备：
将基材展开，在它的表面上涂布含氟聚合物层，涂布之后通过固化得到太阳能电池背板。
本发明方法采取的固化方法包括通过紫外线照射使含氟聚合物交联固化或通过采用X射线、钴60、静电加速器和大功率电子直线加速器等作为辐照源由高能射线引发含氟聚合物交联固化。
本发明中，含氟聚合物层可以通过浸涂法、气刀涂布法、刮刀涂布法、凹版涂布法、狭缝涂布法等方法涂布在基材上。
太阳能电池背板的厚度为25～50μm，优选30～40μm。

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。
