Newest Generation Front Side Silver Paste Delivers Superior Efficiency for P-type Solar Cells

The latest front side silver paste, DuPont™ Solamet® PV20x designed for P-type solar cells, LDE and PERC which provides further aspect ratio improvement and superior contact.

These advancements are aimed at increasing cell efficiency by more than 0.1 percent.

DuPont™ Solamet® PV20x features include:

  • Enhanced organic design improves fine line printing with better aspect ratio
  • Enables extreme Lightly Doped Emitters (LDE) by reducing contact resistance and optimizes overall cell performance as a result of fill factor (FF) and open circuit voltage (Voc) improvement
