About PV Ribbon

PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.

1, Tabbing Ribbon

Tabbing Ribbon commonly connects the positive and negative sides of the cells in series.

2, Bus bar Ribbon

Bus bar Ribbon concentrates the cell stringing into junction box and channels electrical current.
