Description

一种高反射焊带的制作方法
技术领域
本发明涉及光伏电池技术领域,具体涉及一种高反射焊带的制作方法。
背景技术
光伏焊带又称涂锡铜带或镀锡铜带,是光伏组件焊接过程中的重要原材料,分为汇流带和互连条,应用于光伏组件电池片之间的连接,发挥导电聚电的重要作用。焊带质量的好坏将直接影响到光伏组件电流的收集效率,对光伏组件的功率影响很大。
现有的光伏组件大多采用的涂锡焊带为普通涂锡铜带。涂锡铜带的可焊性能好,其采用优质的铜基材,电阻率低,保证了焊带电阻值低,不会引起组件功率损耗;同时还具有稳定的化学性能,焊料良好的流动和低温性能;且焊带表面光洁光亮,无锡渣,无针孔,无露铜;但涂锡铜带反射率较低,而电池片被涂锡铜带覆盖部分无法吸收太阳光,电池片可利用的反射光较少,故无法提高组件效率。
发明内容
本发明的目的是提供一种高反射焊带的制作方法,解决了现有普通涂锡铜带反射率不好的问题。
为实现上述目的,本发明采用以下技术方案:
一种高反射焊带的制作方法,包括如下步骤:
步骤1:设定光伏电池板带有主栅线的面为正面;
步骤2:将光伏电池板进行涂覆、串焊和固化操作;
步骤3:将光伏电池板进行组件排串和层叠加工。
所述步骤2的具体步骤如下:
步骤S1:将光伏电池板进行串焊,将串焊好的光伏电池板平放在操作台上,并将光伏电池板的正面朝上;
步骤S2:将高反射涂料以点胶、滚涂或喷涂的方法涂覆在光伏电池板的主栅线上的涂锡焊带上;
步骤S3:将涂覆好高反射涂料的光伏电池板放入固化炉,进行固化。
所述步骤2的具体步骤如下:
步骤S4:将涂锡焊带的长度裁剪为290mm;
步骤S5:将高反射涂料以点胶、滚涂或喷涂的方法涂覆在涂锡焊带上,其涂覆长度为120mm~160mm;
步骤S6:将涂覆好的涂锡焊带放入固化炉进行固化,其固化温度为100度~160度,固化时间为1分钟~15分钟;
步骤S7:利用固化好的涂锡焊带对光伏电池板进行串焊操作。
所述高反射涂料为BaSO4、BaCO3、TiO2、ZnO、CaCO3和ZrO2中的一种或几种的混合物。
所述高反射涂料在涂锡焊带上的涂覆厚度为5μm~200μm。
本发明所述的一种高反射焊带的制作方法,解决了现有普通涂锡铜带反射率不好的问题;本发明在普通涂锡铜带上涂覆白色高反射涂料,提高了涂锡焊带的反射率,简化了制作工艺流程。
