existPhotovoltaic Industry<\/a>In the chain,Photovoltaic welding ribbon<\/a>As an important part of photovoltaic modules, it belongs to the electrical connection part and is mainly used in photovoltaic modules.Solar Cells<\/a>The series or parallel connection plays an important role in collecting current and conducting electrical energy, ensuring the stability of the output voltage and power of the photovoltaic modules.<\/p>\n

In a photovoltaic module, solar cells are connected through photovoltaic welding ribbons to form a complete circuit loop, and then packaged with EVA\/POE film, photovoltaic glass, backplane, frame, silicone and other materials to form a photovoltaic module.<\/p>\n

First of all, from the structure of photovoltaic welding ribbon, it is composed of substrate and surface coating:<\/p>\n

(1) The base material is copper of different specifications, which requires precise specifications, good conductivity and certain strength<\/p>\n

(2) 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. Special processes such as electroplating, vacuum deposition, spraying or hot-dip plating can be used. 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 line of the battery, thereby playing a good role in current conduction.<\/p>\n

2. From the classification of photovoltaic ribbons: According to the product application direction, it can be divided into interconnection ribbons and busbar ribbons. For conventional photovoltaic modules, the consumption ratio of interconnection ribbons and busbar ribbons is about 4:1; for multi-door modules, the consumption ratio of interconnection ribbons and busbar ribbons is about 5:1.<\/p>\n

(1) Interconnection strip: It is a tin-coated solder strip used to connect photovoltaic cells, collect and transmit the current of photovoltaic cells. As the conductive lead strip of the solar cell, it is directly welded to the front and rear grid lines of the battery, connecting the positive and negative electrodes of adjacent batteries to form a series circuit, converting the light energy on the battery into electrical energy and leading it to the electrical equipment, while also playing a role in heat dissipation.<\/p>\n

According to the performance and applicable fields of photovoltaic welding ribbons, the interconnecting strips mainly include conventional interconnecting strips, MBB welding ribbons, SMBB welding ribbons, low-temperature welding ribbons, low-resistance welding ribbons, etc.<\/p>\n

(2) Busbar: It is a tin-coated solder strip used to connect photovoltaic cell strings and junction boxes to transmit the current of photovoltaic cell strings. Photovoltaic cells are connected in series to form a battery string, and the busbar is used to connect many battery strings to achieve a complete circuit.<\/p>\n

According to the performance and applicable fields of photovoltaic welding ribbons, busbar welding ribbons mainly include conventional busbar welding ribbons, punching welding ribbons, black welding ribbons, bent welding ribbons, etc.<\/p>\n
