Photovoltaic welding ribbon<\/a>AsPhotovoltaic modules<\/a>The performance of photovoltaic ribbon directly affects the current collection efficiency and overall power generation performance of photovoltaic modules. In the selection and use of photovoltaic ribbon, there are several key performance indicators that need to be paid attention to to ensure the quality and applicability of the ribbon. The following are several performances that need special attention during the use of photovoltaic ribbon.<\/p>\n

1. Electrical conductivity<\/strong><\/p>\n

The main function of photovoltaic ribbon is to connect the cells and conduct electricity, so its conductivity is the primary consideration. Good conductivity can reduce resistance loss and maximize the power generation efficiency of the module. The material of the ribbon is usually high-purity copper or tinned copper to ensure its excellent conductivity.<\/p>\n

Note:<\/p>\n

Choose a material with high conductivity, such as copper.<\/p>\n

The uniformity of the plating also affects the conductive properties, ensuring the thickness and uniformity of the tin or silver plating layer.<\/p>\n

2. Antioxidant properties<\/strong><\/p>\n

Photovoltaic modules are used outdoors for a long time, and the soldering tape needs to be exposed to the air and faces the threat of oxidation. Soldering tape with poor oxidation resistance is prone to oxidation during use, resulting in reduced conductivity at the welding point, which affects the service life of the module. Therefore, the surface of high-quality soldering tape needs to be plated, such as tin plating or silver plating, to enhance its oxidation resistance.<\/p>\n

Note:<\/p>\n

The quality and thickness of the coating determine the oxidation resistance of the welding strip. Usually, the coating is required to be uniform and free of bubbles and voids.<\/p>\n

Antioxidant properties are particularly important in high temperature and high humidity environments.<\/p>\n

3. Mechanical strength and flexibility<\/strong><\/p>\n

The soldering tape needs to withstand mechanical stress during welding, so mechanical strength and flexibility are properties that must be considered. The flexibility of the soldering tape can ensure that it will not break easily during welding, while its mechanical strength can ensure that it is not easily deformed and damaged during installation and transportation.<\/p>\n

Note:<\/p>\n

Choose the appropriate annealing process to ensure the softness of the solder ribbon, especially when manual soldering requires a soft solder ribbon.<\/p>\n

The automated welding process requires the welding ribbon to have a certain hardness and linearity to improve welding efficiency and reliability.<\/p>\n

4. Welding performance<\/strong><\/p>\n

Photovoltaic welding ribbons must have good welding performance to ensure reliable connection between cells. Surface treatment of the welding ribbon, such as tin plating, can effectively improve welding performance, ensure that the welding is firm and not easy to fall off, and the welding is uniform and has good conductivity.<\/p>\n

Note:<\/p>\n

The welding temperature should be within an appropriate range. Too high or too low a temperature will affect the welding effect.<\/p>\n

When choosing a lead-free soldering process, the surface treatment of the solder ribbon and the matching of the flux are very important.<\/p>\n

5. Corrosion resistance<\/strong><\/p>\n

Photovoltaic modules are exposed outdoors for a long time and need to withstand harsh environments such as wind, rain, and salt spray. The welding strips need to have strong corrosion resistance. The quality of the coating is the key to affecting the corrosion resistance. The thicker the coating, the better the corrosion resistance of the welding strip.<\/p>\n

Note:<\/p>\n

In high humidity and high salt environments, the corrosion resistance of the welding strip is particularly important, and the quality and thickness of the coating need to be strictly controlled.<\/p>\n

Choose welding strip materials that have undergone special anti-corrosion treatment to extend service life.<\/p>\n

6. Accuracy of dimensions and specifications<\/strong><\/p>\n

The width, thickness, length and other dimensions of the photovoltaic ribbon directly affect the welding effect and the performance of the photovoltaic module. Too thick or too thin ribbons will affect the welding effect and reduce the power generation efficiency. Therefore, the size of the ribbon needs to be completely matched with the design of the battery cell.<\/p>\n

Note:<\/p>\n

The width of the solder strip should match the width of the main grid line of the battery cell.<\/p>\n

Choose the appropriate thickness of the soldering tape to ensure firm welding and avoid false welding.<\/p>\n

7. Surface finish<\/strong><\/p>\n

The surface finish of the welding strip will directly affect the quality of welding. Especially in automated welding, the rough surface of the welding strip will affect the stability of the equipment and even cause welding failure.<\/p>\n

Note:<\/p>\n

Ensure that the surface of the soldering tape is smooth, free of scratches and impurities.<\/p>\n

The plating process is uniform and flawless, ensuring stable welding quality.<\/p>\n

in conclusion<\/p>\n

Photovoltaic welding ribbon is an indispensable and important part of photovoltaic modules. Its performance directly affects the overall power generation efficiency and service life of the photovoltaic system. When selecting welding ribbon, in addition to conductivity, it is also necessary to consider multiple performance indicators such as oxidation resistance, welding performance, and mechanical strength.Raytron<\/a>As a professionalPhotovoltaic ribbon supplier<\/a>, with many years of production experience, can provide customers with high-quality welding ribbons to help photovoltaic modules improve overall performance, reduce losses and extend service life.<\/p>","protected":false},"excerpt":{"rendered":"
