Photovoltaic welding ribbon<\/a>existPhotovoltaic modules<\/a>It plays a very critical role in the photovoltaic industry. It is mainly used to connect the cells in the photovoltaic module and connect the cells in series to form a battery string. Photovoltaic welding ribbon is also calledTinned copper strip<\/a>, photovoltaic welding ribbon is divided intoSolar Convergence Strip<\/a>And solar interconnect strips. Its role is to collect and transmit the current of photovoltaic cells, ensuring that the current can flow efficiently from one cell to another and finally converge at the output end.<\/p>\n

The quality of photovoltaic welding ribbon directly affects the current collection efficiency of photovoltaic modules. If the quality of the welding ribbon is poor, it may cause the connection between the cells to be loose and cause a cold solder joint, thus affecting the overall performance of the photovoltaic module. Therefore, during the production process, manufacturers must select suitable photovoltaic welding ribbons and determine the state of the welding ribbon to be used based on the characteristics of the selected cells.<\/p>\n

When choosing a suitable welding tape, the thickness of the tape is generally determined according to the thickness of the battery cell and the size of the short-circuit current. The width of the tape should be consistent with the width of the battery main grid to ensure that the current can be transmitted smoothly. In addition, the hardness of the tape usually depends on the thickness of the battery cell and the welding tool.<\/p>\n

There are two types of photovoltaic ribbons: interconnection strips and busbars. Interconnection strips are used to connect cells in series and are welded on the main grid of the cell. They are mainly responsible for collecting and transmitting the current of the photovoltaic cell. Busbars are used to connect the photovoltaic cell string and the junction box. They do not directly contact the cell and are mainly used to transmit the current of the photovoltaic cell string.<\/p>\n
