Manufacturing process of IBC battery assembly

Abstract

The invention provides a manufacturing process of an IBC battery assembly. The manufacturing process improves the assembly efficiency of the battery assembly, ensures the yield and further ensures thepower generation efficiency of IBC battery pieces. The process comprises the following specific steps: S1,carrying out laser cutting: firstly, carrying out laser cutting on a whole battery piece, andforming (n-1) laser scratches on the battery piece to make the battery piece divided into n small battery pieces; S2, coating insulating glue : presetting a certain number of extraction electrodes onareas arranged along the length direction at the two sides of each of the n small battery pieces, and meanwhile, coating the peripheries of the extraction electrodes with insulating glue; S3, curingthe insulating glue: curing the battery pieces coated with the insulating glue; S4, coating solder paste: coating the solder paste at the positions of the corresponding preset extraction electrodes onthe small battery pieces; S5, arranging the battery pieces: arranging the small battery pieces in a positive-negative series connection manner; S6, placing a series solder strip; and S7, welding thesolder strip: welding the solder strip and the solder paste at the corresponding positions to conduct the solder strip and the solder paste.

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...
