AI Technical Summary

Technical Problem

In existing technologies, the welding quality of the solar cell solder strips is poor, resulting in incomplete welding between the solder strips and the solar cells, poor welding stability, and affecting the power generation efficiency and lifespan of the solar cells.

Method used

A battery cell processing device is used to heat and extrude the welding strip and battery cell through a pressure mechanism, so that the welding strip is welded to the battery cell at high temperature. The self-heating capacity or thermal conductivity of the pressure component is used to improve the welding effect.

Benefits of technology

This improves the welding contact between the solder strip and the solar cell, enhances the stability of the solder strip, and thus improves the welding quality of the solar cell solder strip.
