Solar Cell Interconnect Wire Designed for Conductive Adhesives

A family of highly engineered solar tabbing and interconnect wire has been developed to work specifically with conductive adhesives, pastes and tapes.  As solar module manufacturers innovate to improve performance, Ulbrich has been a trusted partner working tirelessly to engineer PV Ribbon products that will outperform the competition.  This new family of products has both a smooth surfaced product, similar in appearance to traditional ribbon and highly innovative grooved wire improving output by up to 4%.

LCR-XP™ and LCR-SP™ are the high efficiency grooved solar cell tabbing/interconnect wire that replace traditional smooth wire used to connect solar cells together within a module.  Both were developed to increase the efficiency of a solar module by reflecting more light back onto the surface of the cell.  This innovative grooved interconnect wire steers the reflected light back to the glass/air interface allowing total internal reflection back onto the cell surface.  Up to 80% of the incoming light that strikes the LCR™ ribbon is recovered significantly higher than the 5% recovery of traditional solar cell tabbing and interconnect wire.

EasyBond-XP™ and EasyBond™ are our smooth surface solar cell tabbing/interconnect products that have been engineered with specific properties to improve the conductive adhesive manufacturing process as well as improve total output.

 LCR™ Delivers High Output

  • XP is Silver plated for maximum reflectivity and conductivity
  • SP is Tin Plated for high reflectivity and conductivity
  • Engineered lower yield  strength copper wire to prevent cell damage during stringing process
  • Compatible with current manufacturing processes with minimal retooling
  • Application Engineers design LCR products to satisfy each clients’ unique needs and specifications
  • Improved Aesthetics – uniformly dark cells for improved appearance
  • Low Coefficient of thermal expansion (low yield) for minimal internal stress  (day/night effect) prevents cell breakage during extreme temperature changes and variations.
  • Up to 4% increase in solar module power output*
  • Increased power output of up to 2% from grooved ribbon recapture and up to 2% with increase is wire thickness and width for up to 4% total power output.
  • LCR-XP™ Wire can be made in varying cross sections to reduce resistive losses, maximizing current output, without compromising module efficiency.



*actual efficiencies can vary depending on design.
