Abstract

The invention discloses a photovoltaic module and a manufacturing method thereof, and the method comprises the following steps: placing a plurality of interconnection structural members on the surface of one side of a battery piece, enabling one end, corresponding to a first bonding pad, of each interconnection structural member to extend to one side, which exceeds the edge, adjacent to the battery piece, of the first bonding pad, a plurality of bonding pads are arranged between each interconnection structural member and the battery piece, and the bonding pad closest to the edge of one side of the battery piece in the plurality of bonding pads is a first bonding pad; judging whether the actual length L1 of each interconnection structural member is equal to the theoretical length L of the interconnection structural member or not; if L1 is equal to L, keeping the position of the corresponding interconnection structural member unchanged; if L1 is less than L, moving the corresponding interconnection structural member towards the direction of the edge of the battery piece; and if L1 is greater than L, moving the corresponding interconnection structural member towards the direction far away from the edge of the battery piece. According to the manufacturing method of the photovoltaic module provided by the invention, the deviation correction of the interconnected structural member can be realized, and the reliability of the photovoltaic module is improved.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic manufacturing, in particular to a photovoltaic component and a manufacturing method thereof. Background technique [0002] In the related art, in order to improve the output power of photovoltaic modules, segmented welding tapes are usually used to connect adjacent cells. However, the segmented ribbon has periodicity, and factors such as the fluctuation of the cycle length of the ribbon and the difference in the extension of the ribbon may cause a certain difference between the actual length of the ribbon and the theoretical length. SUMMARY 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 method for manufacturing a photovoltaic module, which can realize the deviation correction of the interconnection structure when the actual length and the th...
