Beschreibung
Zusammenfassung:	The invention discloses a back contact solar module and an electrode soldering method therefor. 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 on a solder pad of each of the two solar cells. 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 inner stress induced by the soldering for the electrode pads or by a following lamination packaging, which solves the problem in the prior art that the inner residual stress in an electrode solder part harmfully affects the electrical connection between solar cells.
