The adjacent two sub-battery pieces are mutually overlapped and then connected through the welding strip, although the problem of battery string open circuit caused by the breakage and hidden cracking of the battery pieces can be solved, the welding strip exists at the overlapped part of the sub-battery pieces, the thickness of the welding strip is too large (about 0.23mm thick), and the sub-battery pieces are caused by hidden cracking or breakage due to the stress of the welding strip in the process of laminating the assembly. Through research, the inventor finds that the problems of damage, hidden crack and broken circuit of a battery string can be solved as long as the thickness of the welding strip is reduced, the connection between adjacent sub-battery pieces can be ensured, and meanwhile, the overlapping area between the adjacent sub-battery pieces can be reduced as the bonding material is removed, and the overall thickness of the photovoltaic module is also reduced.
