Back-Contact photovoltaic cells can be said to be the photovoltaic cells of tomorrow, as the future of the wind, Back-Contact soral cells dedicated to the PV ribbon needs to have a series of characteristics, used to meet the needs of this advanced photovoltaic cell technology.
One of the characteristics of BC PV cells is that the electrodes are located on the back of the cell, so the PV ribbon must have excellent conductivity to ensure that the current can be conducted efficiently.
Thin and wide design:
The electrodes of BC PV cells are typically wider and thinner than those of conventional cells. Therefore, the design of the PV ribbon needs to accommodate these special dimensions to ensure accurate and robust welding.
Good corrosion resistance:
Since the electrodes of BC PV cells are located on the backside of the cell, the solar cell tab wire may be subject to different environmental conditions and potential corrosion threats. Therefore, the welding tapes need to be corrosion resistant to ensure reliable long-term performance.
High temperature stability:
BC PV cells typically operate at high temperatures, so solar cell tab wire needs to have excellent high-temperature stability to prevent performance degradation.
Tape must adhere securely to the back of the cell to ensure that current can be reliably transferred between the cell and the cell connector.
The PV ribbon needs to be malleable to accommodate the curved design of BC PV cells.
High thermal conductivity:
Good thermal conductivity helps the PV ribbon to distribute heat more evenly during the welding process, ensuring quality and stability of the weld.
Considering sustainability and environmental protection, PV ribbon for BC PV cells should preferably be recyclable to reduce resource waste.
Compliance with relevant standards:
PV ribbon needs to comply with international and industry standards to ensure product quality and performance.
In short, PV ribbon for BC PV cells needs to have special characteristics in a number of areas, such as electrical conductivity, dimensions, corrosion resistance, high temperature stability, adhesion, malleability, thermal conductivity, recyclability, etc., in order to meet the needs of BC PV cell technology. These characteristics help to ensure the high efficiency performance and long term reliability of BC PV cells. raytron, as the industry’s top pv ribbon supplier with top quality products, is the best partner for BC PV cell manufacturers.
