Multibusbar Flat Ribbon

M9-M12 round wire

Top - Bottom Busbar


It is widely used in the solar industry to connect solar cells together in a solar module. It is a thin and flexible tin/silver coated ribbon that is placed on the front and back of a solar cell and soldered to create a series connection between the cells.

Round ribbons are responsible for conducting the direct current that the cells collected from solar photons to the solar inverter. Round ribbons first of all lead partially to reduce in the shading losses compared to flat ribbons. In addition to that, they also increase the reflectance of incident lights into the interface of the glass and the front encapsulant layer of a PV module. Therefore, the use of this technique can result in both increasing the output power and also the efficiency of the PV module.
