Photovoltaic welding ribbon<\/a>It is to apply a uniform layer of tin-based solder on the surface of the copper strip. According to the purpose, it can be divided into interconnection strips (connecting cells and soldering to cells on the grid line) and busbars (connecting battery strings and junction boxes).Tinned copper strip<\/a>It is generally composed of copper as the main substrate and tin alloy coating.<\/p>\n

The interconnection bar is used to connect the battery string and is welded on the main grid line of the battery.Photovoltaic cells<\/a>The sedimentation belt is used to connect the photovoltaic cell string and the junction box. It does not come into direct contact with the cell and has the function of transmitting the photovoltaic cell string current.<\/p>\n

Photovoltaic welding ribbon is used for electrical connection of photovoltaic cell packaging and is one of the core raw materials of photovoltaic modules. Its appearance, size, mechanical properties, surface structure, resistivity and other performance indicators will directly affect the current collection efficiency of photovoltaic modules and have a great impact on the power of photovoltaic modules.<\/p>\n

Photovoltaic ribbon isSolar Photovoltaic<\/a>A sub-segment of the industry, it has the characteristics of "small industry, big market". my country's photovoltaic welding tape industry is relatively well developed, dominated by private enterprises, and the market structure is relatively stable. Matching the distribution area of downstream photovoltaic module manufacturers, my country's photovoltaic welding tape companies are mainly concentrated in Jiangsu and Zhejiang.<\/p>\n

The application of welding ribbons in photovoltaic modules is mainly divided into interconnection strips and busbars. Interconnection welding ribbons mainly include conventional flat welding ribbons, MBB welding ribbons, low-temperature welding ribbons, low-resistance welding ribbons, special-shaped welding ribbons, etc.; busbar welding ribbons mainly include conventional busbar welding ribbons, stamping welding ribbons, black welding ribbons, bent welding ribbons, etc. At present, the mainstream photovoltaic welding ribbon products on the market are MBB welding ribbons for multi-grid modules, with a diameter of 0.28~0.35mm, which is thinner than the previous 5BB conventional flat welding ribbons, which is conducive to reducing the shading of the battery cells and making more effective use of sunlight. Increasing the number of main grids is conducive to shortening the lateral collection path of the battery cells, reducing the series resistance, and reducing the power loss of the battery cells.<\/p>","protected":false},"excerpt":{"rendered":"
