太阳能电池片及其制备方法、光伏组件
摘要：
本发明提供了一种太阳能电池片，其表面设有若干主栅，其特征在于：所述太阳能电池片的边缘设有若干与所述主栅相对应的贯通槽。本发明通过在所述太阳能电池片的边缘开设贯通槽，可以减少太阳能电池片在焊接及层压过程中的隐裂现象，并且当所述太阳能电池片通过互联条串联成电池串时，所述贯通槽用以容纳至少部分串联相邻的太阳能电池片的互联条，从而相邻的太阳能电池片之间预留很小的片间距或无须设置片间距即可实现串联。
摘要（英）：

The invention provides a solar cell, which is provided with a plurality of main grids on the surface, and is characterized in that the edge of the solar cell is provided with a plurality of through grooves corresponding to the main grids. According to the invention, the through grooves are formed in the edge of the solar cell, so that the hidden crack phenomenon of the solar cell in the welding and laminating process can be reduced, and when the solar cells are connected in series into a cell string through interconnection strips, the through grooves are used for accommodating at least part ofthe interconnection strips for connecting the adjacent solar cells in series, so that the adjacent solar cells can be connected in series by reserving a very small space between the adjacent solar cells or without setting the space between the adjacent solar cells.
