Photovoltaic welding ribbon<\/a>existPhotovoltaic modules<\/a>In applications, it is mainly divided into interconnection strips and busbars. Interconnection strips mainly include conventional flat strips, MBB strips, low-temperature strips, low-resistance strips, special-shaped strips, etc.; busbars mainly include conventional busbars, perforated strips, black strips, curved strips, etc. At present, the mainstream photovoltaic welding strip products on the market are MBB welding strips for multi-grid components, with a diameter of 0.28~0.35mm, which is thinner than the previous 5BB conventional flat welding strips, which is conducive to reducing the shading of the battery cells and making more effective use of sunlight. Increasing the number of main grids is conducive to shortening the lateral current collection path of the battery cells, reducing the series resistance, and reducing the power loss of the battery cells.<\/p>\n
| category<\/td>\n | variety<\/td>\n | Applicable fields<\/td>\n | Features<\/td>\n<\/tr>\n |
| Interconnection strip<\/td>\n | Conventional welding strip<\/td>\n | Suitable for general<\/td>\n | It has excellent properties such as low yield strength and high tensile strength, meeting the needs of conventional components<\/td>\n<\/tr>\n |
| MBB welding ribbon<\/td>\n | Applicable to multi-grid modules<\/td>\n | Thinner than conventional welding ribbons, more and thinner shed wires are beneficial to reduce shading of the battery cells, more effectively utilize sunlight, and make the current density distribution more uniform. The power of the component will be significantly increased by 5-8W, and the front silver of the battery can be reduced by about 30%<\/td>\n<\/tr>\n | |
| Low temperature solder strip<\/td>\n | Applicable to HJI battery components<\/td>\n | Changing the coating composition of conventional solder strips and using solder with a melting point not exceeding 175\u00b0C as raw material can achieve low-temperature welding and help reduce the welding temperature of heterojunction battery strings.<\/td>\n<\/tr>\n | |
| Low resistance welding strip<\/td>\n | For conventional components<\/td>\n | By reducing and precisely controlling the coating thickness, the resistance of the solder strip is reduced, and the power loss caused by the series resistance of the module is reduced. When replacing the traditional solder strip, there is no need to change the module production equipment, process and materials, but the module power can be increased by about 0.3%<\/td>\n<\/tr>\n | |
| Special-shaped welding strip<\/td>\n | Suitable for multi-shed components<\/td>\n | The product features a section with a special-shaped structure, which is used for the front of the cell, and can reflect sunlight to the maximum extent, thus increasing the power of the module; the adjacent section is a relatively thin and wide flat structure, which is used for the back of the cell. This can not only reduce the cell spacing, but also reduce the thickness of the encapsulation film on the back of the module, which is conducive to reducing the cost of the module.<\/td>\n<\/tr>\n | |
| Busbar<\/td>\n | Conventional busbar<\/td>\n | For conventional components<\/td>\n | We have coil-mounted and shaft-mounted busbar products to meet the production needs of PV modules.<\/td>\n<\/tr>\n |
| Punching welding strip<\/td>\n | Applicable to shingled modules<\/td>\n | The shingled welding strip is punched again to form a hollow welding strip in the middle, which is used to connect the battery cells of the shingled module. Punching helps to reduce the stress of the welding strip on the battery cell and reduce fragments.<\/td>\n<\/tr>\n | |
| Black welding ribbon<\/td>\n | Suitable for all-black components<\/td>\n | Color matching is carried out according to the appearance requirements of the components to maintain the consistency of the appearance of the welding strips, component frames and solar cells. This is to achieve the purpose of aesthetics and reduce optical pollution.<\/td>\n<\/tr>\n | |
| Bending welding strip<\/td>\n | For conventional components<\/td>\n | The common busbar is bent 90 degrees in the plane to replace two busbars that are spot-welded to each other, thereby improving the production efficiency of component customers and reducing the manufacturing cost of photovoltaic components.<\/td>\n<\/tr>\n | |
| Shingled welding strip<\/td>\n | Applicable to shingled modules<\/td>\n | The shingled ribbon is thinner and has a lower yield strength. It can be used in high-density shingled modules and can be welded with thinner cells. The shingled ribbon can be flipped to achieve a smaller module format without increasing the cell fragmentation rate. It reduces module costs and improves module performance per unit area.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>","protected":false},"excerpt":{"rendered":" Photovoltaic welding ribbons are mainly divided into interconnection strips and busbars in photovoltaic module applications.
