RAYTRON<\/a>It is currently the top domesticTinned copper strip manufacturers<\/a>, with 10 high-precision 4-row rolling mills, the annual production capacity can reach 10,000 tons. As a professional domestic tinned copper strip manufacturer, we provide professional products to meet the production needs of various enterprises.<\/p>\n

Production of tinned copper strip orPhotovoltaic welding ribbon<\/a>The main cost, among which the raw material cost can be said to be the main cost of photovoltaic welding ribbon. As we all know, we can divide the tinned copper ribbon into interconnection strip and busbar. The interconnection strip is used to connectPhotovoltaic cells<\/a>We usually use busbars to connect photovoltaic cell strings and junction boxes.<\/p>\n

We usually use copper-based materials, tin alloy coatings and flux to make photovoltaic ribbons through processing. However, the cost of raw materials accounts for more than 90% of the production cost. The production of photovoltaic carbon ribbons starts with the release of copper-based materials for rolling. Then annealing, fluxing, and finally tinning are performed to obtain the finished product.<\/p>\n

We usually use various types of photovoltaic ribbons, and MBB ribbons are more common. According to different performance and application fields, we can divide photovoltaic ribbons into many types. Interconnection strips mainly include conventional interconnection strips, MBB ribbons, low temperature ribbons, low resistance ribbons, etc.; busbars mainly include conventional busbars, perforated ribbons, black ribbons, curved ribbons, etc.<\/p>\n

At present, the mainstream photovoltaic ribbon products on the market are MBB ribbons. They are suitable for multi-grid modules. Because it is thinner than traditional ribbons, it helps to reduce the shading of the cells and use the sunlight more efficiently. At the same time, increasing the number of main grids helps to shorten the lateral current collection path in the cell. Reduce the series resistance and reduce the power loss of the cell.<\/p>\n
