PV ribbon, as a key material for PV modules, has a direct impact on the performance and lifetime of the PV module. Therefore, PV ribbons are usually made of high-purity copper (oxygen-free copper) or aluminium. These metallic materials have good electrical conductivity and mechanical properties and are ideally suited for connecting the cells and rows of cells in a solar module.
In addition to the material, there are a series of criteria that can be controlled for reference, which manufacturers need to understand clearly in order to know how to identify the good and bad PV ribbon.
The conductivity of PV ribbon is directly related to the efficiency of current conduction. A good quality PV ribbon should have good conductivity to ensure efficient power generation of PV modules.
Considering the application of PV modules in different environmental conditions, PV ribbon needs to have good corrosion resistance to prevent oxidation and corrosion caused by environmental factors.
Conductive layer adhesion:
The adhesion between the PV ribbon and the conductive layer of the cell is critical to the stability and life of the module. Selecting a ribbon with good adhesion to the conductive layer reduces heat loss due to increased contact resistance.
The solderability of PV ribbon is directly related to productivity and solder quality. Welding ribbons with good solderability can increase productivity and reduce production costs.
PV modules may be subject to external forces during transport, installation and use, so the tensile strength of the ribbon needs to be sufficient to ensure the stability of the module structure.
Select PV ribbon with relevant quality certifications, such as the International Electrotechnical Commission (IEC) and other certifications, to ensure that it meets international standards and has reliable quality.
Choose a manufacturer with good reputation and rich experience. Well-known manufacturers are usually able to provide more reliable products and have stronger after-sales service and technical support.
Considering price, performance, quality and other aspects, choose a PV ribbon with good cost-effectiveness to ensure the cost-effectiveness of the investment.
When selecting PV ribbon, it is necessary to comprehensively consider factors such as conductivity, corrosion resistance, conductive layer adhesion, solderability, tensile strength, quality certification, manufacturer’s reputation and cost-effectiveness to ensure that high-quality ribbons are selected to meet the requirements of PV modules.
