Abstract

The invention provides a solder strip of a double-sided reflective structure and a manufacturing method thereof, the top of the solder strip is of a triangular structure, the bottom of the solder strip is of a rectangular structure, the directions of the tops of every two adjacent solder strips are opposite, and the joint of every two adjacent solder strips is of a flat structure. The structure enables the solder strip to have a double-sided reflective effect, the directions of the bottom surfaces of two adjacent sections of the double-sided reflective solder strip are opposite, the solder strip can be well connected with the positive electrode surface and the negative electrode surface of a battery piece, after the connected battery string is packaged, the solder strips on the front and back surfaces of the solder strip have reflective effects, and the power of the front and back surfaces of the battery can be simultaneously improved. The thickness of the solder strip between two adjacent sections is reduced after the solder strip is rolled, so that the adverse effect of the solder strip on the edge of the battery piece can be avoided, the distance between the battery pieces can be reduced by adjusting the thickness of the solder strip at the position, and the conversion efficiency is improved.

Description

technical field

[0001] The invention relates to the field of welding strips, in particular to a welding strip with a double-sided reflective structure. Background technique

[0002] As energy is increasingly exhausted, solar energy, as a renewable energy source, has attracted more and more attention. In recent years, the photovoltaic industry has developed rapidly, and the competition in the industry has become increasingly fierce. Photovoltaic modules are currently developing in the direction of how to increase the efficiency of modules. High-efficiency modules are the general trend of future industry development. It is currently a direction to develop high-efficiency modules by optimizing the structure of the ribbon to increase the use of light on the surface of the cell to increase the power of the module.

[0003] Commonly used ribbons for photovoltaic modules are flat. When sunlight shines on the surface of the ribbon, the light will be reflected outside the module. Th...
