What is a PV ribbon?

PV ribbon is a hot-dip tinned copper conductor that collects current from photovoltaic cells and is the conductor that joins the individual solar cells and carries the current generated to the distribution system. There are two main types of PV ribbon: interconnect ribbon and bus bar ribbon.

What are the different types of PV ribbon?

There are two main types of PV ribbon: interconnect ribbon and bus bar ribbon. Interconnect ribbon carries the generated current from all the PV cells to the bus bar. Then the bus bar ribbon carries the accumulated current to the junction box or electrical distribution system.

What is a PV interconnect ribbon?

Interconnect ribbon carries the generated current from all the PV cells to the bus bar. Then the bus bar ribbon carries the accumulated current to the junction box or electrical distribution system. PV interconnect ribbon is 1to 3mm in width, with thickness in the range of 0.085 to 0.2mm.

How strong is a PV ribbon?

The values of our PV Ribbon are lower than 65 N/mm2 yield strength and more than 25% elongation at fracture. Not easy to achieve - but possible with Ulbrich! Ulbrich has extensive capabilities and scientific resources to achieve the optimum conductive solutions for thin film modules.

How thick is PV interconnect ribbon?

PV interconnect ribbon is 1to 3mm in width, with thickness in the range of 0.085 to 0.2mm. Bus bar ribbon is larger than interconnect ribbon at 3 to 6mm in width and 0.2 to 0.5mm thick. The primary material of PV ribbon is usually copper.

What elongation is best for PV ribbon?

Elongation: A higher elongation is more effective for PV ribbon because the higher ductility will better withstand contraction and expansion cycles due to outdoor temperatures. When selecting a PV ribbon it is best to look for elongation that is at least 20% or as high as possible for greatest PV ribbon reliability.
