Abstract: A welding method for a welding strip of a back-contact solar cell chip includes the following steps: firstly, welding small chip assemblies of a back-contact solar cell to be interconnected to form a small cell string through an interconnected bar; then, punching the small cell string into small cell assemblies separated from each other through a cutting or punching process; subsequently, flexibly welding the small cell assemblies by a bus bar to reach a required length of a finished assembly product; and finally, breaking the bus bar through a post cutting or punching process to form cell assemblies with positive and negative electrodes connected in series or in parallel. The method makes the welding surfaces of the solar cell chips be on the same surface through using the back-contact solar cell chips, so that the interconnected bar of the solar cell chips can be welded rapidly and continuously.
