Beschreibung
Zusammenfassung:	A composition for solar cell electrodes and a solar cell electrode fabricated using the composition, the composition including a conductive powder; a glass frit; an organic vehicle; and a surface tension modifier, wherein the surface tension modifier has a surface tension of about 40 mN/m to about 65 mN/m, and the composition has a thixotropic index (TI) of about 3 to about 10 as represented by Equation 1: TI=(viscosity at 10 rpm/viscosity at 100 rpm), [Equation 1] in Equation 1, the thixotropic index is calculated using viscosity values of the composition measured at 10 rpm and 100 rpm and at 23° C. with a No. 14 Spindle using a rotary viscometer.
