Description

一种太阳能组件用凹凸焊带
技术领域
本发明涉及太阳能组件技术领域，具体涉及一种太阳能组件用凹凸焊带。
背景技术
太阳能电池片通过焊带连接后，通过焊带传输电流，但随着电池片厚度日益变薄，由焊带和电池片之间在焊接前后的热涨冷缩产生的应力很容易导致电池片破裂，大幅增加光伏组件的损耗，传统光伏组件中的焊带设于电池片正反两面，焊带受光照射，焊带的使用寿命较低，电池片正面有焊带会造成一定程度的光电转化损失，也就是说正面的焊带会遮挡一部分的电池片，这影响了太阳能组件的光电转换效率。
发明内容
为解决上述技术问题，本发明的目的在于提供一种太阳能组件用凹凸焊带，使焊带均焊接于电池片背面，降低焊接后的应力，减少电池片的破裂，延长焊带的使用寿命。 
为达到上述目的，本发明的技术方案如下：一种太阳能组件用凹凸焊带，包括凹凸焊带本体，所述凹凸焊带本体上等间距设有下凹块，所述凹块旁为向上的弧度凸起，所述凹块个数和所述弧度凸起个数至少为一个。
优选地，所述凹块为4个，所述弧度凸起为4个。
优选地，所述凹块为3个，所述弧度凸起为3个。
优选地，所述凹凸焊带本体的厚度为0.08mm-0.5mm。
优选地，所述凹凸焊带本体的宽度为1mm及以上。
采用以上技术方案的有益效果是：由于焊带本体上设有弧度凸起，能够减小电池片焊接前后热胀冷缩产生的应力，由于焊带本体上设有凹块，能将电池片正面的接点引入到电池片背面，这样所有焊带均铺设于电池片背面，正面没有焊带，不会出现焊带遮挡一部分电池片的问题，电池片光电转换效率提高了，同时也延长了焊带的使用寿命，且电池正面均一、美观，满足消费者的审美需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1
如图1、图2、图3和图4所示，一种太阳能组件用凹凸焊带，包括凹凸焊带本体，所述凹凸焊带本体上等间距设有下凹块3，所述凹块3旁为向上的弧度凸起3，焊带本体上有4个凹块2和4个弧度凸起3，凹凸焊带本体的厚度为0.08mm-0.5mm，凹凸焊带本体的宽度为1mm，凹凸焊带本体设于一片电池片1上，电池片1正面在焊接点处打孔，电池片1正面的接点通过孔引到电池片1背面，与电池片1背面的凹凸焊带的凹块2焊接，背面电池片1和凹凸焊带本体之间设有绝缘垫片4，此时弧度凸起3方向朝下，电池片1背面的接点与凹凸焊带本体的凹块2焊接，此时凹凸焊带本体的弧度凸起3朝上，与背面的电池片接点连接，这样电池片1正面和背面的接点都在电池片背面与凹凸焊带本体焊接，弧度凸起3能够减小电池片焊接前后热胀冷缩产生的应力。
实施例2
如图5和图6所示，其余与实施例1相同，不同之处在于，电池片1为两片，是两片电池片与凹凸焊带的组件。
实施例3
如图7所述，其余与实施例1相同，不同之处在于，所述凹凸焊带本体的凹块2为3个，所述凹凸焊带本体的弧度凸起3为3个。
采用以上技术方案的有益效果是：由于焊带本体上设有弧度凸起，能够减小电池片焊接前后热胀冷缩产生的应力，由于焊带本体上设有凹块，能将电池片正面的接点引入到电池片背面，这样所有焊带均铺设于电池片背面，正面没有焊带，不会出现焊带遮挡一部分电池片的问题，电池片光电转换效率提高了，同时也延长了焊带的使用寿命，且电池正面均一、美观，满足消费者的审美需求。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
