Abstract

The invention discloses a segmented light condensing welding strip applied to a photovoltaic module. The segmented light condensing welding strip comprises a first-segment welding strip and a second-segment welding strip, wherein a sloping grain light reflection layer is arranged on the upper surface of the first-segment welding strip, a welding layer is arranged on the lower surface of the first-segment welding strip, and one side surface of the second-segment welding strip and one side surface of the first-segment welding strip are mutually laminated and connected. By virtue of the structureof the sloping grain light reflection layer, the light income of the surface of the battery can be effectively increased, so that the power output of an assembly is improved and can be equal to the power gain of a light reflection film strip; the difference between the segmented light condensing welding strip and a welding process of a conventional interlinked strip is small, compared with a light reflection film strip product, the welding procedure is not increased, the advantages of the light condensing welding strip and the film strip are integrated, the problems of poor aging property anduse reliability are avoided, the safe use and production are guaranteed, the power gain is increased, and the product income is increased.

Description

Technical field [0001] The invention relates to the technical field of welding ribbons, in particular to a segmented concentrating welding ribbon applied to photovoltaic modules. Background technique [0002] With the development of solar photovoltaic cell and module technology, the demand for high-efficiency modules is becoming more and more urgent. In order to obtain higher module power output, research has been done on the structural direction of interconnection strips that realize cell interconnection. The derived products include various embossed structure concentrating soldering tape (ie interconnecting strip) products and reflective film tape products . [0003] The existing concentrating soldering tape products are realized by mechanical extrusion on the copper substrate with different embossed patterns on the Cu base, and then by electroplating or hot dip coating on the copper substrate with a layer of welding coating (Usually tin-lead layer), to achieve the secondary re...
