Description

用于叠瓦组件的电池片及其测试方法 技术领域
本发明涉及光伏电池技术领域，具体地，涉及用于叠瓦组件的电池片及其测试方法。
背景技术
随着全球技术和经济的迅猛发展，日益需要更多更清洁的能源来满足需求。太阳能发电时没有二氧化碳排出并且环境负担小，因此许多国家和地区都在大力发展太阳能(光伏)电池作为能源。
光伏电池是利用光电效应将光能转化为电能的器件，最常见的是晶体硅电池，通常为片状。在光伏电池中，栅线是重要组成部分，其负责将电池内部产生的电流汇集传送至电池外部。叠瓦组件是基于叠片技术的高性能、高密度光伏电池组件，与传统的光伏电池组件相比，叠瓦组件通过将光伏电池片以更紧密的方式互相连接，使一个电池片的正面主栅线与另一个电池片背面的背面主栅线重叠，令电池间的缝隙降到最低，从而有效地减少了由于电池间隔造成的非有效发电空间，因此在同样的单位面积中可以铺设更多电池，增加吸光面积，提高光伏组件的转换效率，并且由于电池片之间不需要焊带连接，减少了组件的串阻，进而在提高组件功率的同时还节省了焊带的成本。
由于叠瓦组件的制作工艺要求，用于叠瓦组件的电池片的栅线设计与常规电池片有很大区别。如图1和图2所示，在现有的用于叠瓦组件的电池片中，电池片正面具有多条正面主栅线，并且这多条正面主栅线最外侧的两条正面主栅线1通常设计在电池片的边缘位置，而电池片背面具有多个背面主栅线，最外侧的两个背面主栅线2通常位于电池片的非边缘位置。对于这种设计，现有的测试工装不适合对其进行测试，其主要原因在于，测试时正面探针要下压到电池片的正面主栅线上，而由于多条正面主栅线最外侧的两条正 面主栅线位于电池片的边缘，这大大增加了电池片隐裂以及破片的可能性。
发明内容
本发明针对以上现有技术中存在的问题，提供一种用于叠瓦组件的电池片及其测试方法。
根据本发明的一个优选实施方式，用于叠瓦组件的电池片具有正面和与所述正面相对的背面，多条正面主栅线形成于电池片的正面并且彼此平行地延伸，所述多条正面主栅线中的最外侧两条正面主栅线没有位于所述电池片的边缘位置，多条背面主栅线形成于电池片的背面并且平行于所述多条正面主栅线延伸。
根据本发明的一个优选实施方式，电池片的形状为大致正方形，多条正面主栅线和多条背面主栅线的延伸方向平行于正方形的一组平行边。
根据本发明的一个优选实施方式，电池片还包括位于电池片的正面并与多条正面主栅线相交的多条正面细栅线。
根据本发明的一个优选实施方式，正面主栅线和正面细栅线大致垂直。
根据本发明的一个优选实施方式，多条正面主栅线、多条正面细栅线和多条背面主栅线的材料包括银，背电场位于电池片的背面上紧邻多条背面主栅线的位置，背电场的材料包括铝。
根据本发明的一个优选实施方式，对用于叠瓦组件的电池片进行测试的测试方法包括以下步骤：提供上测试装置，使上测试装置位于电池片的正面与正面主栅线接触并导通；提供下测试装置，使下测试装置位于电池片的背面与背面主栅线接触并导通；将上测试装置和下测试装置电连接到测试设备以进行测试。
根据本发明的一个优选实施方式，下测试装置还与背电场接触并导通。
根据本发明的一个优选实施方式，上测试装置包括多个上探针 排，每个上探针排包括多个探针。
根据本发明的一个优选实施方式，多条正面主栅线中彼此邻近的两条正面主栅线同时与一个上探针排接触并导通。
根据本发明的一个优选实施方式，下测试装置为多个下探针排，每个下探针排包括多个探针。
根据本发明的一个优选实施方式，下测试装置为板状测试装置。
根据本发明的一个优选实施方式，板状测试装置为单个矩形板或多个条形板。
根据本发明的一个优选实施方式，板状测试装置为镀金铜板。
根据本发明的一个优选实施方式，利用所述测试方法对所述电池片进行效率测试和电致发光筛选测试。
本发明所提供的用于叠瓦组件的电池片，由于其多条正面主栅线中最外侧的两条正面主栅线设计在电池片的非边缘区域，能够利用现有测试工装进行转换效率测试和电致发光(EL)筛选测试而不会造成隐裂和破片。同时，本发明所提供的针对本发明电池片的测试方法也大大降低了电池片隐裂和破片的可能性。

具体实施方式
下面，参照附图详细描述本发明的用于叠瓦组件的电池片及其测试方法。这里所描述的仅仅是根据本发明的优选实施方式，本领域技术人员可以在所述优选实施方式的基础上想到能够实现本发明的其他方式，所述其他方式同样落入本发明的范围。
以下详细描述中出现的方位术语，例如“上”、“下”、“左”、“右”等是指具体附图中的方位。
本发明提供一种用于叠瓦组件的电池片。所述电池片具有正面和与所述正面相对的背面，多条正面主栅线形成于电池片的正面并且彼此平行地延伸，所述多条正面主栅线中的最外侧两条正面主栅线没有位于所述电池片的边缘位置，多条背面主栅线形成于电池片的背面并且平行于所述多条正面主栅线延伸。具体地，图3和图4分别示出了根据本发明的一个优选实施方式的电池片3的正面视图和背面视图。如图3所示，电池片3的形状为大致正方形，多条正面主栅线1均沿着平行于电池片3的一组平行边的方向延伸，所述方向在图中示出为纵向方向，通过图3还可以看见，在电池片的正面还有与正面主栅线1相交的多条正面细栅线，正面细栅线主要用于收集电池片所产生的电流并通过正面主栅线1输送到电池外部加以利用，图3中正面细栅线与正面主栅线是大致垂直相交的，但这仅仅是为了方便示出，在本发明的电池片上正面细栅线还可以以其他角度与正面主栅线相交，例如以45度倾斜相交。如图3所示，所述多条正面主栅线1均位于电池片的非边缘位置，其中有两条正面主栅线1(图3中左侧)彼此邻近。如图4所示，电池片的背面有多条背面主栅线2彼此平行地沿着与多条正面主栅线1的延伸方向平 行的方向延伸，并且在紧邻背面主栅线2的位置具有背电场8。正面主栅线、正面细栅线与背面主栅线的主要材料一般为银，而背电场的主要材料一般为铝。
本发明还提供用于对本发明的电池片进行测试的测试方法，其中需要用到上测试装置和下测试装置分别接触电池片的正面和背面以进行测试，具体如图5-图8所示，如图中所示方向，上面为电池片的正面，下面为电池片的背面。
图5为采用根据本发明的一个优选实施方式的测试方法测试时沿图3中线A-A(正面主栅线1的位置)截取的截面视图。其中，3为电池片，位于电池片3上面的为正面主栅线1，位于电池片3下面的为背面主栅线2，位于最上侧与正面主栅线1接触并导通的为上测试装置10，位于最下侧与背面主栅线2接触并导通的为下测试装置20，上测试装置10和下测试装置20均与常规使用的测试设备电连接以对电池片3进行转换效率测试和电致发光(EL)筛选测试等其他测试。在图5所示的优选实施方式中，上测试装置10包括具有多个探针5的多个上探针排4，下测试装置20包括具有多个探针7的多个下探针排6。现在通过另一个方向的截面视图6来进一步说明，图6为采用以上所述测试方法时沿图3中线B-B截取的截面视图，由图中可见，在测试时，探针5与正面主栅线1接触并导通，其中通过选择合适的探针，可以仅通过一排探针5同时接触多条正面主栅线中彼此邻近的两条正面主栅线1并与其导通(图6中左侧)，探针7在与探针5大致对应的位置与背面主栅线2和背电场8接触并导通，在这种情况下，电池片的正面和背面的受力情况相对均匀且受力点对应，不会产生使电池片发生变形的力矩，被测试的电池片不易发生隐裂和破片等不希望发生的情况。
当然，可以想到，探针还可以以其他的方式布置在电池片上以实现同样的目的，例如，图7中示出了本发明的测试方法的另一个优选实施方式，与图6相比，探针7的布置位置有所不同，具体而言，靠近左右两侧的两排探针7布置在了电池片的边缘位置，此时， 所有探针7均与背面主栅线2接触并导通。这样布置增加了对电池片边缘的承托，避免电池片受力不均，被测试的电池片不易发生隐裂和破片等不希望发生的情况。
优选地，还可以采用其他形式的下测试装置来代替如上所述的下探针排6和探针7。图8是采用根据本发明的又一个优选实施方式的测试方法测试时沿图3中线A-A截取的截面视图，在该优选实施方式中，下测试装置包括板状测试装置9，由于其具有较大的接触面积，在测试时对电池片背面施加的接触压强会大大降低，从而保护电池片不会隐裂和破片。可以想到，所述板状测试装置9可以是与电池片的形状尺寸相当的单个矩形板状件，也可以是多个条形的板状件或者其他形状的板状件，只要具有足够的接触面积即可。根据本发明的一个优选实施方式，所述板状测试装置9可以是镀金铜板。
利用以上所述的测试方法，能够有效地对本发明的电池片进行转换效率测试和EL筛选测试等其他测试，减少电池片的浪费。
需要注意的是，在如上所述的本发明的优选实施例中，正面主栅线、背面主栅线、探针排以及探针的数量仅仅是示例性的，对本发明的保护范围不具有任何限定作用，可以根据具体情况而采取其他的任意数量。
本发明的保护范围仅由权利要求限定。得益于本发明的教导，本领域技术人员容易认识到可将本发明所公开结构的替代结构作为可行的替代实施方式，并且可将本发明所公开的实施方式进行组合以产生新的实施方式，它们同样落入所附权利要求书的范围内。
