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.
