The present invention relates to a silver paste composition for forming an electrode, and a silicon solar cell using the same. More particularly, the present invention relates to a silver paste composition for forming an electrode, which includes carbon black having specific parameter characteristics to improve rheological properties of the paste and printability, thereby achieving a high aspect ratio and improving electrical characteristics, and a silicon solar cell using the same.

Silver paste composition for forming an electrode, and silicon solar cell using same

The present invention relates to a conductive metal ink composition which is properly applied for roll-printing process to form conductive pattern with improved conductivity, and the method of preparing a conductive pattern using the same. The conductive metal ink composition comprises a conductive metal powder; an organic silver complex where an organic ligand including amine group and hydroxyl group binds with a silver (Ag) salt of aliphatic carboxylic acid; 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.
