Solamet® PV17x Series Helps Set New Standard for Solar Cell Efficiency

DuPont offers a new series of frontside silver photovoltaic metallization pastes to deliver advanced efficiency and adhesion for solar cells.  DuPont™ Solamet® PV17x series photovoltaic metallizations also will enable higher process reliability and yield for both cell and module manufacturers. Compatible with LDE (Lightly Doped Emitter) profiles, high-speed printing processes, and featuring improved contact and grid resistance.

Solamet® PV17x series benefits:

  • Improved efficiency over DuPont™ Solamet® PV16x family*
  • Compatible with LDE
  • Reduced junction damage
  • Excellent solderability and consistent soldered adhesion
  • Low laydown
  • Fast drying and firing
  • Excellent fine line capabilities
  • High electrical conductivity after firing

* Solamet® PV17x delivers up to 0.5 percent improved efficiency over PV16A through improved series resistance, and achieves results more cost-effectively, because it requires 15 percent lower material consumption.  

Cell manufacturers can expect to achieve 50 to 70 micron finger line widths at high print speeds. Solamet® PV17x exhibits exceptional solderability and adhesion which enables reliable use in the highly automated tabbing and stringing processes used by module makers.

DuPont™ Solamet® Front Side Silver Photovoltaic Metallization Pastes – Double Print

DuPont™ Solamet® metallization pastes for double-printing maximize efficiency of the cell by enabling narrower and taller grid lines to be precisely printed in two or more layers, reducing the shadowing effect of wide grid lines on solar cells and improving electrical conductivity.
