PV ribbon for cells is a tinned copper ribbon installed in photovoltaic solar panels. The interconnect ribbon is soldered directly onto silicon crystal to interconnect solar cells in a solar panel. The PV bus bar is installed around the perimeter of the solar panel and connects the interconnect ribbons to the junction box.
Solar cell soldering ribbon
About PV solar cells Ribbon:
PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.
Tabbing Ribbon: it is commonly connects the positive and negative sides of the cells in series.
Bus bar Ribbon: it is concentrate the cell stringing into junction box and channels electrical current.
