Solar ribbon for photovoltaic modules

Competence & Innovation

Solar ribbon for photovoltaic modules

BRUKER-SPALECK is a leading manufacturer of high-quality flat wires for solder joints for all solar module technologies. The solder joint as a flat wire is also variously described as solar ribbon, cell connectors, tabbing, straight connectors, cross connectors, bussing and string connectors. The development of the flat wires as a connector ranges from 3BB through 4BB, 5BB to 6BB solar cells. New technologies are round wires and white high-efficiency solar ribbon. The flat wire solar ribbons are also available in other colors such as black – depending on the BIPV project.

Bruker-Spaleck PV Ribbon String Bussing

With the Bruker-Spaleck high-efficiency solar ribbon (HE solar ribbon), you can increase module efficiency by up to 1.3% of annual energy yield.

Explain function principle

  • The white paint reduces the level of optical loss through the principle of total internal reflection

    Higher quantum yield compared to conventional connectors

Paint

  • White

Sequences

  • The paint is also applied to the standard cell connectors
