Front Side AG Metallization Paste for Solar Cell (SN908X)

LEED SN928X is an environmental conductive paste designed on silicon solar cell(n+) positive electrode. The conductive component in silver paste will be the excellent ohmic contact characteristics with silicon chip penetrating SiNx film, with good printing, low contact resistance, high resolving power and high fill factor.
