DuPont™ Solamet® PV3N2 Photovoltaic Metallization Paste for N-Type Cells

Solamet® PV3N2 photovoltaic metallization is a high efficiency paste for N-Type wafers. It is designed for contacting a B-doped p-type emitter. It is capable of firing through dielectric passivation/ARC layer and contacting p-type boron-doped emitter giving low contact resistivity. PV3N2 is also co-fireable with silver conductors such as DuPont™ Solamet® PV17x, PV18x.


  • Fine-line printability (for gridlines with screen printing)
  • Fire-through passivation layer
  • Better contact on B-doped emitter layer, enabling a broader diffusion process window
  • Low gridline resistivity (high conductivity)
  • Flexibility in metallization process selection. Proven technology on double-print design
  • Co-fireable with rear side contacts
  • Good solderability and adhesion
  • Cadmium free*
