Segmentation series welding process of solar cell

Abstract

The invention discloses a segmentation series welding process of a solar cell, which comprises the following steps of: segmenting the whole solar cell into a plurality of segments, paving and segmenting conductive connecting pieces on the segments, and performing lap joint series welding on the segments to form a cell string. Thus, the segmentation efficiency of the whole solar cell can be improved, and the fragmentation productivity is improved; the cutting efficiency of the conductive connecting piece can be improved; and the overlapping efficiency, the welding efficiency and the productivity of the cell string can be improved.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a process for dividing and stringing solar cells. Background technique [0002] With the development of solar cell technology, it appears that the entire battery sheet (such as a square sheet or a quasi-square sheet) is divided into multiple slices, and then the battery string is prepared from the slices. [0003] At present, the preparation of sliced ​​battery strings is generally to cut off the ribbon piece by piece and overlap the pieces one by one. To the outside of the segment, the next segment is overlapped on the small section of the ribbon, and so on, until the entire battery string is overlapped. It can be seen that the ribbon needs to be cut once every time a segment is overlapped, so the ribbon needs to be cut multiple times to overlap a battery string, resulting in low efficiency of battery string preparation. Contents of the invention [0004] In order to solve the d...

Problems solved by technology

It can be seen that every time a segment is overlapped, the ribbon needs to be cut once, so the ribbon needs to be cut several times to overlap a battery string, resulting in low efficiency of battery string preparation
