光伏用背面浮法玻璃及双玻组件
相关申请
本发明申请要求2016年06月20日申请的，申请号为201620618406.0，名称为“光伏用背面浮法玻璃及双玻组件”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本发明涉及光伏技术领域，具体而言，涉及一种光伏用背面浮法玻璃及双玻组件。
背景技术
在光伏组件的制备工艺中，为了防止层压工序可能出现的太阳电池串移位，进而造成良品率下降的问题，通用的方法是采用透明高温胶带黏贴相邻太阳电池串的方式，但是，这种方式额外增加了工序，不利于生产效率的提升，而且，当各个太阳电池串随封装胶膜收缩向中心移动时，透明高温胶带将会失去作用。
发明内容
基于此，有必要提供一种光伏用背面浮法玻璃及双玻组件，可以有效解决现有技术中透明高温胶带对太阳电池串定位效果差的问题。
一种光伏用背面浮法玻璃，用于与太阳电池串实现配合，包括玻璃基材和设置在玻璃基材朝向太阳电池串一侧表面的玻璃凸粒。
在其中一个实施例中，玻璃凸粒设置在相邻的太阳电池串之间的间隙处。
在其中一个实施例中，各相邻的两个太阳电池串之间的玻璃凸粒数量相同。
在其中一个实施例中，位于同一列太阳电池串间隙处的玻璃凸粒同列对齐设置。
在其中一个实施例中，各相邻的两个太阳电池串的两相邻电池片之间的玻璃凸粒数量为两个，沿同一方向分别设置在太阳电池串的电池片长度方向的三分之一处和三分之二处。
在其中一个实施例中，玻璃凸粒的高度低于光伏组件层压后正面和背面两玻璃间距。
在其中一个实施例中，玻璃凸粒的高度为光伏组件层压后正面和背面两玻璃间距的二分之一至三分之二。
在其中一个实施例中，在玻璃基材位于太阳电池串的外侧的部分设置有玻璃凸粒。
在其中一个实施例中，玻璃凸粒为白色。
在其中一个实施例中，玻璃凸粒的熔点低于玻璃基材的熔点。
一种双玻组件，包括光伏用背面浮法玻璃和太阳电池串，以及正面压花玻璃、封装胶膜， 该光伏用背面浮法玻璃为上述的光伏用背面浮法玻璃，光伏用背面浮法玻璃的玻璃凸粒朝向太阳电池串。
本发明提供的光伏用背面浮法玻璃用于与太阳电池串实现配合，包括玻璃基材和设置在玻璃基材朝向太阳电池串一侧表面的玻璃凸粒，玻璃凸粒的熔点低于玻璃基材的熔点。在双玻组件的制备过程中，可以通过玻璃凸粒固定太阳电池串，避免电池串在层压过程的抽气环节及熔融态封装胶膜的流动过程中发生移位，完全避免透明高温胶带黏贴过程中异物及破片发生的可能性，减少工序，压缩工人数量，还可以提高双玻组件的生产效率。。
附图说明
为了使本发明的内容更容易被清楚的理解，下面根据本发明的具体实施例并结合附图，对本发明作进一步详细的说明，其中
图1是本发明的光伏用背面浮法玻璃的结构示意图；
图2是本发明的双玻组件太阳电池串排版示意图；
图3是本发明的双玻组件的结构示意图。
图中：1、玻璃基材；2、玻璃凸粒；3、太阳电池串；4、正面压花玻璃。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
结合参见图1至图3所示，根据本发明的实施例，光伏用背面浮法玻璃用于与太阳电池串3实现配合，包括玻璃基材1和设置在玻璃基材1朝向太阳电池串3一侧表面的玻璃凸粒2。
优选地，玻璃凸粒2的熔点低于玻璃基材1的熔点。
根据太阳电池串3排版的要求，将双玻组件用的背面浮法玻璃朝向太阳电池片的一面制作具有一定排布规则、一定数量的低熔点玻璃凸粒2，在双玻组件的制备过程中，可以通过玻璃凸粒2固定太阳电池串3，避免太阳电池串3在层压过程的抽气环节及熔融态封装胶膜的流动过程中发生移位，完全避免透明高温胶带黏贴过程中异物及破片发生的可能性，减少工序，压缩工人数量，还可以提高双玻组件的生产效率。该低熔点玻璃凸粒3是在光伏玻璃出厂前制作，不是在双玻组件制备过程中制作，该低熔点玻璃凸粒，其熔点相对于玻璃基材较低，但在光伏组件制备过程中(如层压工序)不会熔融。
玻璃凸粒2设置在相邻的太阳电池串3之间的间隙处，可以对位于玻璃凸粒2两侧的太阳电池串3形成定位，防止两侧的太阳电池串3向玻璃凸粒2所在方位发生位移，通过多个 玻璃凸粒2相互作用，可以对各太阳电池串3均起到良好的定位作用。
各相邻的两个太阳电池串3之间的玻璃凸粒2数量相同，可以提高玻璃凸粒2的分布规律性，便于玻璃凸粒2的成型。
位于同一列太阳电池串3间隙处的玻璃凸粒2同列对齐设置，一方面可以使得该列玻璃凸粒2两侧的两列太阳电池串3保持较好的定位，防止层压过程中发生位移，另一方面也便于进行玻璃凸粒2的成型，并使太阳电池串3保持较好的队列，能够更好地提高成型要求。
各相邻的两个太阳电池串3的相邻电池片之间的玻璃凸粒2数量为两个，沿同一方向分别设置在太阳电池串3的电池片长度方向的三分之一处和三分之二处。此结构可以使玻璃凸粒2的数量和位置分布更加合理，可以用较少的玻璃凸粒2达到对太阳电池串的较好定位，提高玻璃凸粒2的定位效果，同时降低玻璃凸粒2的加工成本。
优选地，玻璃凸粒2的高度低于光伏组件层压后正面和背面两玻璃间距，可以防止玻璃凸粒2的高度过高而对太阳电池串3的层压形成阻碍，提高太阳电池串3层压时的安全性。
在本实施例中，玻璃凸粒2的高度为光伏组件层压后正面和背面两玻璃间距的二分之一至三分之二。
在玻璃基材1位于太阳电池串3的外侧的部分设置有玻璃凸粒2，可以对太阳电池串3的内侧和外侧均进行有效定位，从而对太阳电池串3进行更加全面有效的限位，防止位于边缘的太阳电池串3向外侧发生位移，进一步提高对太阳电池串3的定位作用。
优选地，玻璃凸粒2为白色，可以有效提高双玻组件的光电转换效率。
根据本发明的另一方面，提供了一种双玻组件，包括光伏用背面浮法玻璃、正面压花玻璃4和太阳电池串3，太阳电池串3设置在正面压花玻璃4上，该光伏用背面浮法玻璃为上述的光伏用背面浮法玻璃，光伏用背面浮法玻璃的玻璃凸粒2朝向太阳电池串3。
由于光伏玻璃基材及太阳电池片的尺寸规格的不同，排版方式也会有所差异，因而要求双玻组件所用背面浮法玻璃上的低熔点玻璃凸粒的尺寸、位置及数量也会不同。下面我们以尺寸为1650mm(L)*985mm(W)*3.2mm(H)的光伏玻璃(含正面压花玻璃及背面浮法玻璃)，尺寸为156mm*156mm*0.2mm的太阳电池片为例，设计一种排版方式，并根据此排版方式和封装胶膜的厚度(以厚度为0.6mm左右的EVA胶膜为例)来确定低熔点玻璃凸粒的具体排列规则、尺寸和数量。
1、排版方式的确定：
一块双玻组件中，尺寸为1650mm(L)*985mm(W)*3.2mm(H)的光伏玻璃，要求尺寸为156mm*156mm*0.2mm太阳电池片有60片，其中每10片串联焊接成1串，共6串。电池串间距为4.2mm，最外侧两电池串分别距离光伏玻璃长边边缘为14mm。
2.低熔点玻璃凸粒的确定：
由于单层EVA胶膜的厚度在0.6mm左右，太阳电池片的厚度约为0.2mm，层压后的双玻组件正面、背面两玻璃间的距离约为1mm，低熔点玻璃凸粒的高度理论上可设计为0.2-1.0mm，但考虑误差的因素，实际操作过程中设计为0.5mm。由于低熔点玻璃凸粒在相邻的电池串之间及最外侧电池串的外边缘位置，因而对其尺寸也有要求。由于相邻两电池串的间隔为4.2mm，低熔点玻璃凸粒2的宽度也有要求，如果宽度太大，在盖上背面浮法玻璃时低熔点玻璃凸粒2可能会碰到甚至压碎电池片，宽度太小，电池串活动空间过大，起不到限定其位置的作用，在实际操作过程中，可以将低熔点玻璃凸粒2的宽度设计为3.2mm。对于低熔点玻璃凸粒2的长度可以根据需要设定。低熔点玻璃凸粒2的数量也可以根据需要确定。EVA为乙烯-醋酸乙烯共聚物(也称为乙烯-乙酸乙烯共聚物)，是由乙烯(E)和乙酸乙烯(VA)共聚而制得，英文名称为：Ethylene Vinyl Acetate，简称为EVA，E/VAC，聚合方法用高压本体聚合(塑料用)、溶液聚合(PVC加工助剂)、乳液聚合(粘合剂)、悬浮聚合，乙酸乙烯(VA)含量高于30％的采用乳液聚合，乙酸乙烯含量低的就用高压本体聚合。
3.低熔点玻璃凸粒的生产制备
根据确定的排版方式和低熔点玻璃凸粒2的排列规则及尺寸，制作印刷网版；选用低熔点玻璃釉料进行印刷，烘干，进入钢化炉，经高温烧结及快速均匀降温，在玻璃表面形成低熔点玻璃凸粒，并完成钢化。此过程在玻璃出厂前批量完成。
4.双玻组件的制备
由于需要精确定位及人工排版存在的不可控因素，优选使用自动化设备进行排版敷设。之后，经过EL测试、层压、削边、清洁、装接线盒、灌封等工序，双玻组件制作完成。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明的保护范围之中。
