A kind of manufacturing process of IBC battery assembly

Abstract

The invention provides a manufacturing process of an IBC battery assembly, which improves the assembly efficiency of the battery assembly, ensures the yield rate, and further ensures the power generation efficiency of the IBC battery sheet. The specific process steps are as follows: S1. Laser cutting: First, laser cut the entire cell, and form (n-1) laser scratches on the cell, so that the cell is divided into n small cells; S2, coating Insulating glue: preset a certain number of lead-out electrodes on the two sides of n small cells arranged along the length direction, and apply insulating glue on the outer periphery of the lead-out electrodes; S3, curing insulating glue: apply the The cells of the insulating glue are cured; S4, coating solder paste: coating the solder paste on the position of the corresponding preset lead-out electrodes on the small cells; S5, arranging: the small cells are arranged in positive and negative series; Place the series soldering strips; S7, soldering the soldering strips: welding the soldering strips and solder paste at the corresponding positions to make them conductive.

Description

technical field [0001] The invention relates to the technical field of manufacturing IBC battery components, in particular to a manufacturing process of IBC battery components. Background technique [0002] IBC batteries do not have metal electrodes on the light-receiving side of the battery, which can completely eliminate the optical loss on the front side and increase the short-circuit current. All electrodes are distributed on the back of the battery in a cross-fingered manner. The larger metallization area improves the battery fill factor. A good passivation process can increase the open circuit voltage of the battery. [0003] After the cells are serially fabricated into modules, a complete solar cell panel can finally be obtained. Because in the process of connecting the cells in series, the cells need to be connected with ribbons, and the resistance (R) of the ribbon itself will cause a loss of electrical performance. Therefore, how to improve the power generation ef...
