Photovoltaic cells<\/a>We usually use busbars to connect photovoltaic cell strings and junction boxes.<\/p>\nWe 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
