Beschreibung
Zusammenfassung:	Disclosed herein is a composition for solar cell electrodes. The composition includes silver powder; glass frits; and an organic vehicle, wherein the glass frits have a glass transition temperature of about 100° C. to about 300° C. and exhibit an exothermic peak starting temperature of about 200° C. to about 400° C. on a DTA curve in TG-DTA analysis. Solar cell electrodes formed of the composition have high open circuit voltage and short circuit current density, thereby providing excellent conversion efficiency and fill factor.
