Photovoltaic welding ribbon<\/a>yesPhotovoltaic modules<\/a>It is an important accessory used to connect photovoltaic cells and transmit electrical energy. Although this accessory is small, its overall impact is not small. A good photovoltaic welding ribbon can improve the efficiency of the entire photovoltaic cell assembly.<\/p>\n

1. Basic concept of photovoltaic welding ribbon<\/p>\n

Photovoltaic welding ribbon, divided intoSolar Cells<\/a>Interconnection strips and busbars are the electrical connection parts in photovoltaic modules. They are mainly used for series or parallel connection of solar cells, and play an important role in collecting current and conducting electrical energy. Through photovoltaic welding strips, solar cells can be connected together to form a complete circuit loop, thereby ensuring the stability of the output voltage and power of photovoltaic modules.<\/p>\n

2. Structural characteristics of photovoltaic welding ribbon<\/p>\n

Photovoltaic welding ribbon is mainly composed of substrate and surface coating.<\/p>\n

Substrate: The substrate of photovoltaic ribbons usually uses copper of different specifications, which requires precise specifications, good conductivity, and certain strength. Since the copper substrate itself does not have good welding performance, the main function of the surface coating is to make the photovoltaic ribbon meet the weldability and firmly weld the photovoltaic ribbon to the main grid line of the battery, thereby playing a good role in current conduction.<\/p>\n

Surface coating: Surface coating is to evenly wrap the coating materials such as tin alloy on the surface of the copper substrate according to a certain composition ratio and thickness. These coating materials are usually made by special processes such as electroplating, vacuum deposition, spraying or hot dip plating. Since the copper substrate itself does not have good welding performance, the main function of the tin alloy layer is to make the photovoltaic ribbon meet the weldability and firmly weld the photovoltaic ribbon to the main grid of the battery, thereby playing a good role in current conduction.<\/p>\n
