The conductive metal ink composition comprises a conductive metal powder; a non-aqueous solvent comprising a first non-aqueous solvent having a vapor pressure of 3 torr or lower at 25&#xb0; C. and a second non-aqueous solvent having a vapor pressure of higher than 3 torr at 25&#xb0; C.; and a coatability improving polymer and is coated for forming the conductive pattern by the roll printing method.

Disclosed are lead free glass frit powder for manufacturing a silicon solar cell, its producing method, a metal paste composition containing the same and a silicon solar cell. The lead free glass frit powder for manufacturing a silicon solar cell includes BiO; BO; and any one metal oxide selected from the group consisting of ZnO, AlOand BaCO, or mixtures thereof. The glass frit powder is free of lead, and thus, it is environmental friendly. A front electrode of a solar cell formed using the glass frit powder has low resistance against contact with a substrate and high adhesion to the substrate.
