Abstract

The invention discloses a photovoltaic module, and the photovoltaic module comprises a plurality of battery pieces and a plurality of interconnection structural parts. Two adjacent battery pieces in the plurality of battery pieces are respectively a first battery piece and a second battery piece; each interconnection structural part comprises a light reflecting section and connecting sections, theconnecting sections comprise a first connecting section and a second connecting section, the first connecting section and the second connecting section are connected to the two ends of the light reflecting section respectively, at least one part of the first connecting section is in a flat shape, and at least one part of the second connecting section is in a flat shape; the reflecting section isnon-flat, the reflecting section and the second connecting section are both connected to the front surface of the first battery piece, and at least one part of the first connecting section is connected to the back surface of the second battery piece. According to the photovoltaic module provided by the invention, the reflecting sections can be prevented from being positioned on the back surface ofthe battery piece, so that the risk of battery piece cracking can be effectively reduced, firm connection with the front surface of the battery piece can be realized, and the reliability of the photovoltaic module is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic module. Background technique [0002] In the related art, the reflective section of the solder ribbon is usually connected to the front of the battery sheet to improve the output power of the photovoltaic module. However, during the processing of photovoltaic modules, when the length of the solder ribbon is long or offset, part of the reflective segment may be located on the back of the adjacent cell, resulting in the risk of cracks in the cell. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a photovoltaic module, which can prevent the reflective segment from falling into the back of the battery sheet, thereby effectively reducing the risk of cracking. [0004] The photovoltaic module accordi...
