Problems solved by technology

[0002] The traditional photovoltaic ribbon is welded on the cell and connects the adjacent cells. Since the ribbon itself has a certain width, it will cover a part of the light-receiving area of ​​the cell, thereby affecting the utilization of light. In order to increase the power of the battery module, There are a few reflective ribbons. Some reflective structures use reflective strips to attach to the surface of the ribbon, and some are directly formed on the surface of the ribbon and are integrated with the ribbon. However, the reflective structures of these two ribbons are parallel to the reflective surface. In the length direction of the ribbon, generally photovoltaic modules are installed facing south. When the reflective structure of the ribbon reflects sunlight, the angle formed by the direct sunlight is limited, so total reflection cannot be formed, and the conversion efficiency of the module cannot be maximized.

Abstract

The invention provides a photovoltaic welding strip. The photovoltaic welding strip comprises a flat welding strip body, and the surface of the welding strip body is provided with a microstructure reflecting light; the microstructure is formed by a plurality of ribs arranged in parallel, and the included angle between the length direction of the ribs and the length direction of the welding strip body is 30-60 degrees. Compared with the prior art, as the included angle is formed between the length direction of the ribs of the microstructure reflecting light and the length direction of the welding strip body, in accordance with the illumination characteristics of a region where solar energy utilization is centralized, light irradiating the welding strip area can be totally reflected to the surfaces of battery pieces to the greatest extent to be absorbed and utilized again, and the power of a photovoltaic module is improved.
