Description

一种光伏电池组件
技术领域
本发明属于光伏技术领域，具体涉及一种光伏电池组件。
背景技术
光伏组件技术已经十分成熟，典型的单玻光伏组件结构主要由玻璃、EVA、电池方阵、EVA、背板封装而成；典型的双玻组件通过玻璃、EVA、电池方阵、EVA玻璃封装而成。
近年来，各种高效光伏技术层出不穷，比较典型的有多主栅电池片组件、电池片切半的切半组件、电池片切成若干个小片的叠瓦组件等，其中典型的叠瓦组件在电池片间通过导电胶带或导电浆料相互粘结导电。另外一种通过焊带连接的称为并片焊接的技术也开始进行普遍，此技术将电池片切成若干小片，一般为2～8片，电池片间通过焊带连接，电池片间可以无限接近或相互重叠，一般片间距在1～-2mm,其中-2mm表示电池片间重叠区域，以上技术可以提高组件功率及组件效率，发展前景巨大。
以上技术在组件封装过程中由于电池片片交叠或电池片片连接的焊带高度较大，在层压过程中片片交叠及焊带区域会承受较大压力而导致层压的隐裂破片等问题。
发明内容
为了解决上述问题，本发明提供了一种光伏电池组件，避免层压过程中隐裂破片等问题发生。
本发明的技术方案为：一种光伏电池组件，包括前板、前胶膜、电池方阵、背胶膜以及背板，所述电池方阵包括多个电池串，所述电池串包括多个电池片，多个电池片之间通过焊带连接和/或相邻电池片之间相互交叠，所述前板和/或背板由玻璃制成，所述前板和/或背板与焊带位置对应处开设有避让槽，和/或所述前板和/或背板在电池片的交叠区域的位置对应处开设有避让槽。
作为优选，与焊带位置对应处的避让槽的截面呈圆弧形。
作为优选，与电池片的交叠区域的位置对应处的避让槽的截面呈三角形。
作为优选，所述前胶膜和所述背胶膜均为EVA。
与现有技术相比，本发明的有益效果体现在：
本发明中在焊带位置对应的玻璃上开设避让槽，若相邻电池片相互交叠时，在交叠处对应的玻璃上也开设避让槽，通过开设避让槽的方式可以增大玻璃的受力面积，进而减小玻璃对应处的受力大小，避免层压过程中隐裂破片等问题发生，提高产品的合格率。
附图说明
图1为现有技术中典型的单玻或双玻组件层压件结构图。
图2为现有技术中叠瓦或并片组件的结构示意图。
图3为本发明中第一种实施方式(单玻光伏组件)的结构示意图。
图4为本发明中第二种实施方式(双玻光伏组件)的结构示意图
图5为本发明中第三种实施方式的结构示意图
具体实施方式
如图3～图5所示，本发明包括前板1、前胶膜、电池方阵、背胶膜以及背板5，一般前胶膜和所述背胶膜均为EVA。本发明可以为单玻光伏组件，即前板1为玻璃材料制成，本发明也可以为双玻光伏组件，即前板1和背板5均为玻璃材料制成。
本发明中电池方阵的结构形式也有多种，例如电池方阵包括多个电池串，所述电池串包括多个电池片3，多个电池片3之间通过焊带7连接。如图3所示，对于此种电池方阵下的单玻光伏组件来说，本发明中可以在玻璃与焊带位置对应处开设避让槽6，增大玻璃的受力面积，进而减小玻璃对应处的受力大小，避免层压过程中隐裂破片等问题发生，提高产品的合格率。
如图4所示，对于上述电池方阵下的双玻光伏组件来说，本发明中则可以在两侧玻璃与焊带位置对应处分别开设避让槽6，同样起到增大玻璃受力面积的作用，进而减少玻璃的受力大小。其中，避让槽6的结构形式可以有多种，例如避让槽6的截面呈圆弧形。
本发明中电池方阵中，如图5所示，相邻电池片3之间还可以相互交叠，对于此种电池方阵结构下的单玻光伏组件来说，前板1在电池片3的交叠区域的位置对应处开设有避让槽6。对于上述电池方阵结构下的双玻光伏组件来说，则在前板1和后板与交叠取悦位置对应处分别开设避让槽6，起到增大玻璃受力面积的作用，进而减少玻璃的受力大小。其中，避让槽6的截面可以呈三角形。
