Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] The inventors of the present invention found in the process of studying the soldering strip in the above-mentioned prior art that the outer surface of the base material is a flat surface, and in the process of setting the solder layer on the flat outer surface of the base material, the solder is in a liquid state. Due to the action of tension, the solder layer easily forms an outer surface of an outer arc, which in turn causes the outer surface o...

Abstract

The invention provides a solder strip and a solder strip production method, and relates to the technical field of solar photovoltaics. The solder strip includes a substrate; the outer surface of the substrate comprises at least one inner concave surface. In the present application, in a process that the solder layer fills the outer surface of the substrate, due to the tension effect, the welding flux can fill and level up the inner concave face of the outer surface of the substrate well, the outer surface of the welding strip is smooth, and compared with a welding strip with the outer surfacebeing in an outer circle convex shape, the outer surface of the welding strip is smooth, the light reflection effect can be improved possibly, and the conversion efficiency and the power of the photovoltaic module are improved. Meanwhile, the solder strip is not easy to reverse, the effective welding distance between the solder strip and the battery piece is increased, the welding reliability is improved, and the conversion efficiency and the power of the photovoltaic module are further improved.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a welding strip and a production method of the welding strip. Background technique [0002] The reflective ribbon can reflect the light irradiated on the surface of the reflective ribbon, and the reflected light is reflected to the surface of the battery sheet to be absorbed by the battery sheet, which improves the utilization rate of light. Therefore, the reflective ribbon has a wide application prospect. [0003] The reflective ribbon usually includes a base material and a solder layer. After the outer surface of the base material is provided with a solder layer, the outer surface of the reflective ribbon usually presents an outer arc shape. [0004] However, the outer surface of the reflective ribbon is arc-shaped, which easily leads to low conversion efficiency of photovoltaic modules and low power of photovoltaic modules. Contents of the invention [0005] The...
