Photovoltaic welding ribbon<\/a>The working principle isPhotovoltaic modules<\/a>The main function of the welding ribbon in photovoltaic cells and modules is to provide a current transmission path.Solar Cells<\/a>The current is guided from the battery cell to the battery string, and then to the junction box of the photovoltaic module, and finally the power output is realized. The following is a detailed analysis of the working principle of photovoltaic welding ribbon:<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

1. The basic function of welding ribbon<\/strong><\/h3>\n

Photovoltaic welding ribbon is mainly used forConnection between cells<\/strong>Each photovoltaic cell conducts the current it generates through the main grid (or metal grid), and the welding ribbon connects these grids and transmits the current to the busbar or junction box of the entire photovoltaic module.<\/p>\n

Photovoltaic ribbons are usually divided intoInterconnection Ribbon<\/strong>(for connecting the battery cells) andBusbar<\/strong>(Used to connect the cells in series to the junction box.) The function of the welding ribbon is to connect the cells in series and effectively conduct the current they generate, ensuring that the entire photovoltaic module can output electrical energy stably.<\/p>\n

2. How it works<\/strong><\/h3>\n
    \n
  • Current conduction<\/strong>\uff1aPhotovoltaic welding ribbon connects the current generated by each solar cell to the adjacent cells or cell strings through welding. Photovoltaic cells absorb sunlight through the photoelectric effect, generating electrons and holes, thereby generating direct current. These currents are conducted to the welding ribbon through the grid lines of the cells.<\/li>\n
  • Transmission Path<\/strong>\uff1aThe welding ribbon acts as a conductor of current, connecting the current of the cell to other cells in the cell string or to the busbar of the photovoltaic module. The busbar is a metal strip used to connect multiple cell strings and ultimately output the current to the junction box.<\/li>\n
  • Current Collection and Conductivity<\/strong>\uff1aThe welding ribbon needs to ensure efficient conduction of current. The material and design of the welding ribbon will affect its resistance, conductivity and current transmission efficiency. Generally, high-quality welding ribbon materials (such as tinned copper or silver-containing copper) will have lower resistance and better conductivity, thereby reducing power loss and improving the overall efficiency of photovoltaic modules.<\/li>\n<\/ul>\n
