Abstract:
A back contact solar module and an electrode soldering method therefor are disclosed. The back contact solar module includes a substrate, two solar cells formed on the substrate, and a curved solder part. The curved solder part is soldered onto an electrode solder pad of each solar cell. The curved solder part has a curved portion between the two solder pads. The curved portion curves parallel to the substrate. Therefore, the invention utilizes the elasticity in structure or the allowable deformation of the curved portion to release the internal stress induced by the soldering on the electrode pads or by a following lamination packaging, which solves the problem in the prior art that the internal residual stress in an electrode solder part harmfully affects the electrical connection between solar cells.
