Abstract

The invention discloses a condensation welding strip. The condensation welding strip comprises a strip-shaped base, and the strip-shaped base is divided into a plurality of first parts and a pluralityof second parts. The first parts and the second parts are arranged at intervals in sequence in the extending direction of the strip-shaped base. The strip-shaped base comprises a first surface and asecond surface which are arranged oppositely. The first surface located at the first parts is a plane, the second surface located at the first parts is an arc surface, and the first surface and the second surface located at the second parts are both planes. The first surface in the first parts is arranged as a plane and the second surface in the first parts is arranged as an arc surface, the reflection effect of the condensation welding strip on light can be improved, the first surface and the second surface of the second parts are arranged as planes, and the welding stability between the condensation welding strip and a battery panel can be improved.

Description

technical field [0001] The invention relates to the technical field of the photovoltaic industry, and more specifically, to a concentrating welding ribbon. Background technique [0002] With the continuous development of science and technology, solar energy, as a renewable energy source and its advantages of cleanness, has enabled the rapid development of photovoltaic industry technology. [0003] Soldering ribbon occupies an important position in the photovoltaic industry, and is used in the connection between photovoltaic module cells to play the role of conducting electricity and collecting electricity. [0004] Due to the width of the ribbon and the plane surface of the ribbon, the conventional ribbon shields the light of the main grid line of the cell to a certain extent, and cannot be reused. It solves the shading problem of conventional ribbons and improves the conversion efficiency of photovoltaic modules. [0005] The function of the concentrating ribbon is to ref...
