Abstract

The invention discloses a segmented photovoltaic welding strip, and relates to the technical field of photovoltaics. The welding strip comprises a first base material and a first coating covering the surface of the first base material. The first base material comprises a first belt body and a second belt body; the first belt body is provided with a first surface and a second surface which are oppositely arranged; the first surface is connected with the front surface of the first battery piece; the second belt body is connected with the back surface of the second battery piece; the second surface is provided with at least two protruding structures which are arranged in the length direction of the first belt body and extend towards the outer side of the first belt body, and a first groove structure is arranged between every two adjacent protruding structures. The vertical distance between the top of the convex structure and the bottom of the first groove structure is 25-90 microns; the section, in the thickness direction of the first belt body, of the first groove structure is provided with a first bevel edge and a second bevel edge which are opposite, and the included angle between the first bevel edge and the second bevel edge is 70-160 degrees. According to the invention, the light reflection effect can be ensured, the power of the photovoltaic module is improved, and the cost of the photovoltaic module can be reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a segmented photovoltaic welding ribbon. Background technique [0002] Welding ribbon is an important part of photovoltaic modules, which mainly plays the role of connecting cells and cells, cells and junction boxes. Existing welding strips have various shapes, including regular welding strips and irregular shaped welding strips. Special-shaped welding strips have been more widely developed and applied because of their specific advantages that ordinary welding does not have. The existing special-shaped welding tape is usually a triangular or circular structure with a base. This structure has a better light reflection effect, but the overall thickness of the light-reflecting section of the special-shaped welding tape is relatively thick, so that the components need to be used in packaging. Thicker film increases the cost of photovoltaic modules. SUMMARY OF THE INVENTION ...
