BC (Back-Contact) battery-onlyPhotovoltaic welding ribbonA series of features are required to meet this advancedPhotovoltaic cellsTechnology requirements:
1. High conductivity: One of the characteristics of BC cells is that the electrode is located on the back of the cell, so the photovoltaic ribbon must have excellent conductivity to ensure that the current can be conducted efficiently.
2. Thin and wide design: The electrodes of BC cells are usually wider and thinner than traditional cells. Therefore, the design of the photovoltaic ribbon needs to adapt to these special dimensions to ensure the accuracy and firmness of the welding.
3. Good corrosion resistance: Since the electrodes of BC cells are located on the back of the cells, the photovoltaic ribbons may be subject to different environmental conditions and potential corrosion threats. Therefore, the ribbons need to be corrosion-resistant to ensure long-term reliable performance.
4. High temperature stability: BC cells usually operate at high temperatures, so photovoltaic ribbons need to have excellent high temperature stability to prevent performance degradation.
5. Reliable adhesion: The solder ribbon must be able to adhere firmly to the back of the battery to ensure that current can be reliably transmitted between the battery and the battery connector.
6. Plasticity: Photovoltaic welding ribbons need to have a certain degree of plasticity to adapt to the curved design of BC batteries.
7. High thermal conductivity: Good thermal conductivity helps the photovoltaic ribbon to distribute heat more evenly during the welding process, ensuring the quality and stability of welding.
8. Recyclability: Considering sustainability and environmental protection factors, the photovoltaic ribbons dedicated to BC batteries are preferably recyclable to reduce resource waste.
9. Compliance with relevant standards: Photovoltaic welding ribbons need to comply with international and industry standards to ensure the quality and performance of the product.
In short, photovoltaic ribbons dedicated to BC batteries need to have special characteristics in terms of conductivity, size, corrosion resistance, high temperature stability, adhesion, plasticity, thermal conductivity, recyclability, etc. to meet the needs of BC battery technology. These characteristics help ensure the high efficiency and long-term reliability of BC batteries.RaytronAs a leading company in photovoltaic welding ribbons, the photovoltaic welding ribbons we produce are of first-class quality and guaranteed.
