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

Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] The invention provides a process for dividing and stringing photovoltaic cells, which comprises the following steps:

[0023] 1) Lay strip-shaped or strip-shaped conductive connectors on the carrier group along the left and right directions; the carrier group is composed of multiple carriers arranged at equal intervals along the left and right directions, and the carrier is an adsorption carrier; the conductive connection The parts span each carrier; the conductive connecting parts can be welding strips or welding rods;

[0024] 2) Carry out laser cutting on the conductive connector, so that the conductive connector is divided into multiple connector segments arranged i...

Abstract

The invention discloses a segmentation series welding process for photovoltaic cells. The invention discloses a segmentation series welding process of a solar cell. The process comprises the followingsteps of: segmenting a conductive connecting piece into a plurality of connecting piece small sections, paving a whole cell on the connecting piece small sections, segmenting the whole cell into a plurality of fragments, and performing lap joint series welding on the fragments to form a cell string. The cutting efficiency of the conductive connecting piece can be improved; according to the invention, the segmentation efficiency of the whole battery piece can be improved, and the fragmentation productivity is improved; and according to the invention, the overlapping efficiency, the welding efficiency and the productivity of the battery 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 photovoltaic cells. Background technique [0002] With the development of photovoltaic 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 ...
