Bus Bars

Adhesives Research (AR) offers ARclad® electrically conductive pressure-sensitive adhesive (PSA) technology, insulation and coverlay tapes for bus bar applications in solar photovoltaic applications including:

  • Monocrystalline silicon
  • Polycrystalline silicon
  • Amorphous silicon
  • Thin film photovoltaic constructions

ARclad conductive PSAs offer enhanced T-joint stability, conductivity and oxidation characteristics. These tapes offer a firm, cohesive, electrically conductive adhesive that reduces micro movement while withstanding thermal cycling and elevated humidity conditions.

Additionally, the conductive bus bar tapes offer:

  • Stable conductive bonds to electrical contact points under a wide range of environmental conditions
  • Reduced T-joint resistance
  • Lower resistance and excellent joint stability in hot ampacity testing (10 amps, 120°C, 6 days)
  • Good thermal shock performance (IEC 61646, -40 – 85°C)
  • Very stable damp heat resistance (85°C/85% RH)
