Description

technical field

[0001] The invention relates to a welding ribbon in the field of photovoltaic products, in particular to a segmented embossed welding ribbon, a photovoltaic module and a manufacturing method thereof. Background technique

[0002] At present, the surface of the photovoltaic ribbon is mostly smooth and flat. Such a ribbon is conducive to welding with the battery sheet, but the sunlight irradiated on the surface of the flat ribbon is completely reflected, which reduces the absorption of solar light by the battery module. For photoelectric conversion The improvement of efficiency and cell power has a great influence.

[0003] There is also a part of the sawtooth surface welding strip, and the surface of the welding strip is provided with at least one serrated section and at least one smooth section. However, when this type of ribbon is automatically serially welded, it is difficult for the equipment to identify the starting position of the sawtooth section and t...
