Photovoltaic Solar Tabbing Wire

Two and three bus bar technologies have dominated the solar industry, but advanced and more powerful generations of solar cells require new designs and a higher number of bus bars to carry the extra current. Today’s technology includes up to six or more bus bars.

Multi-Tabbing PV Wire

Ulbrich Specialty Wire Products is a world leader in PV Ribbon products. Years ago, we developed Multi-Tabbing PV Wire, a solder coated round wire for high efficiency solar cell modules.

Innovative solar cell concepts require adaptive bus bar technologies that promise efficiency gains, lower series resistance, less shadowing and the reduction of silver consumption.

Two and three bus bar technologies have dominated the solar industry, but advanced and more powerful generations of solar cells require new designs and a higher number of bus bars to carry the extra current. Today’s technology includes up to six or more bus bars.

Multi-Tabbing PV Wire’s small dimension of round wire allows a narrower bus bar width on the solar cell, reducing the shadowing loss with traditional rectangular ribbon, while maintaining optimal power gains for the best output results.

Multi-Tabbing PV Wire offers the same high quality and performance standards you would expect from other Ulbrich products supplied to the PV industry.

Ulbrich Solar Technologies Inc. (UST), is a world leader in PV Ribbon products used to interconnect and transmit current for crystalline silicon and thin film solar cells. For decades, UST has supplied the solar industry with tinned flat copper ribbon while continuously identifying emerging PV Ribbon technologies and engineering innovative solutions to increase the electrical output and performance of solar modules.

Solar Cell Tabbing

Solar Cell Tabbing or Interconnect Wire and Tinned Copper Flat Wire for Solar Cell Modules 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.
