The influence of photovoltaic ribbon on modules and common specifications
2022/03/16
PV ribbons are an essential component of every mainstream solar panel, interconnecting solar cells and providing connections to junction boxes. PV ribbons are tinned copper ribbons with a width of 1-6mm, a thickness of 0.08-0.5mm, and a flux coating of 10-30μm thick.
There are two forms of PV ribbons applied to photovoltaic modules: interconnection ribbons or bus bars and PV bus bars. Both are required in a typical silicon solar cell. Interconnect ribbons are soldered directly to the silicon crystals to interconnect the solar cells in the solar panel. The interconnecting strips bring the current generated by the solar cells to the PV busbars. PV busbars are hot-dip tinned copper conductors installed around the perimeter of the solar panel. PV busbars connect the interconnect strips to the junction boxes. Thin-film solar panels generally require only bus bars.
PV ribbon is a key component in solar panels and an important factor in improving the efficiency and durability of solar panels. The high efficiency and durability of solar panels can only be achieved with high-quality PV ribbons that are properly installed in the solar panel. High-quality PV ribbons can also improve solar panel production efficiency and reduce scrap rates. The quality of PV ribbons and their welding to solar cells is an important factor in ensuring the efficiency and durability of solar panels.
