Solar Cell Tabbing, Interconnect Wire and Tinned Copper Flat Wire for Solar Cell Modules

Solar Cell Tabbing or Interconnect Wire are primarily produced from a tin or tin alloy coated copper flat wire*.  Ulbrich has been producing conductive materials for the photovoltaic industry since 1992, accumulating years of expertise that is applied to each and every order.  A critical feature of Tabbing and Interconnect is lower yield strength and higher elongation.  Our standard ribbon is engineered softer than the inferior higher yield strength ribbon commonly produced.  Our XP Ribbon, capable of larger cross sections, transmits electricity even more efficiently.

Our Solar Cell Tabbing and Interconnect Wire is rolled from round wire in a proprietary process, then solder coated on all four sides.  This combination of processes results in superior coatings and a completely burr free product. Our PV Ribbon products are produced from the highest quality material with each order engineered to your dimensional and physical property specifications.

*other base metals and plating alloys are available
