DuPont Solamet - Model 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.
