  • Demonstrates efficiency gains up to and exceeding 0.15% compared to Solamet® PV18x paste, the current industry benchmark.
  • The first product in the series, Solamet® PV19A paste enables fine line printing down to 30 microns.
  • Improves line aspect ratios to minimize the shading effect on the surface of the solar cell through excellent paste transfer, while maintaining superior electrical conductivity to boost efficiency.
  • Innovative chemistry enables extreme Lightly Doped Emitters (LDE) by reducing contact resistance by an order of magnitude for further electrical improvement
  • Robust processing latitude improves production yields
  • Tighter cell distribution has increased high-efficiency binning to more than 17.8% to support >260 watts of power output*
  • Improves high efficiency cell production yield from 93% to 98.5%*

DuPont continues setting the pace of innovation in the solar industry with more than 110 new Solamet® photovoltaic metallization paste products introduced over the last 7 years, and it is actively developing variants of the new Solamet® PV19x series aimed at boosting solar cell efficiencies even further.
