Document Type and Number:
WIPO Patent Application WO/2024/066719
Kind Code:
A1
Abstract:
A double-sided welding method for a solar cell sheet. The method comprises the following steps: arranging a bearing surface, which has a wire passing groove thereon, on an outer surface of a welding carrier; routing a first strip-shaped electrically-conductive connecting member in the wire passing groove; attaching the cell sheet to the bearing surface; tightly attaching a second strip-shaped electrically-conductive connecting member to an outer side surface of the cell sheet, and then compacting the cell sheet on the first strip-shaped electrically-conductive connecting member, which protrudes from the bearing surface, by means of the second strip-shaped electrically-conductive connecting member; and heating the first strip-shaped electrically-conductive connecting member and the second strip-shaped electrically-conductive connecting member, so as to weld the first strip-shaped electrically-conductive connecting member and the second strip-shaped electrically-conductive connecting member on the cell sheet.
