Beschreibung
Zusammenfassung:	The present invention relates to a composition comprising: silver powder; fumed silica; a glass frit; and an organic vehicle. The composition for forming a solar cell electrode improves contact between an electrode and a wafer by introducing certain fumed silica. In addition, the solar cell electrode produced from the composition demonstrates excellent fill factor and conversion efficiency due to minimized series resistance (Rs).
