Embodiment 1

[0061]In this embodiment, asFigure 1a-Figure 1c withimage 3 As shown, the photovoltaic module is a mosaic module, and there is a gap between the first cell 11 and the second cell 12. From right to left, the interconnect structure 2 includes a reflective section 21, a first transition portion 2222, a first connection portion 2221, a second sub-connection section 2212 and a first sub-connection section 2211 in order. The entire interconnecting structure 2 may be an integrally formed part, that is, the reflective section 21, the first transition portion 2222, the first connection portion 2221, the second sub-connection section 2212, and the first sub-connection section 2211 are integrally formed during the processing. Their materials can be the same, and there is no obvious dividing line. The widths of the first connecting portion 2221, the second sub-connecting section 2212 and the first sub-connecting section 2211 are equal (or very close in width), and both are larger than the width...

Embodiment 2

[0065]In this embodiment, asFigure 2a-Figure 2c withimage 3 As shown, the photovoltaic module is a shingled module, and the end of the first cell 11 and the end of the second cell 12 are overlapped. From right to left, the interconnect structure 2 includes a reflective section 21, a first transition portion 2222, a first connection portion 2221, a fourth sub-connection section 2214 and a third sub-connection section 2213 in order. The entire interconnecting structure 2 can also be an integrally formed part, that is, the reflective section 21, the first transition portion 2222, the first connecting portion 2221, the fourth sub-connecting section 2214, and the third sub-connecting section 2213 are integrally formed during processing. , Their materials can be the same, and there is no obvious dividing line. The widths of the first connecting portion 2221, the fourth sub-connecting section 2214 and the third sub-connecting section 2213 are equal (or very close in width), and both are la...

Abstract

The invention discloses a photovoltaic module, and the photovoltaic module comprises a plurality of battery pieces and a plurality of interconnection structural parts; and two adjacent battery piecesin 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 sectionswhich are connected with each other, the connecting sections comprise a first connecting section and a second connecting section, the first connecting section and the light reflecting section are connected to the two ends of the second connecting section respectively, the first connecting section is flat, and at least one part of the second connecting section is flat; the reflecting section is non-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 section can be prevented from being positioned on the back surface of thebattery piece, the risk of battery piece cracking is effectively reduced, firm connection between the interconnection structural member and the front surface of the battery piece can be realized, andthe 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 cell to increase 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 section may be located on the back of the adjacent cell, resulting in the risk of splitting of the cell.Summary of the invention[0003]The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a photovoltaic module, which can prevent the reflective passage from entering the back of the cell, thereby effectively reducing the risk of splitting.[0004]The photovoltaic module according to the embodiment of the present inventio...
