Composition for forming solar cell electrode and electrode prepared using the same

Abstract

A composition for solar cell electrodes and a solar cell electrode fabricated using the composition, the composition including a conductive powder; a glass frit; and an organic vehicle, wherein the glass frit has a reaction index (RI) of about 0.5 to about 1.0, as calculated according to Equation 1: Reaction index (RI)=Ib/Ia  <Equation 1> wherein, in Equation 1, Ia denotes a maximum peak intensity measured on a specimen at 20.5° to 20.7° (2θ) by XRD analysis, the specimen being obtained by mixing the glass frit with Si3N4 powder in a weight ratio of 1:1 to prepare pellets, followed by heat-treatment at 800° C. for 10 minutes, and Ib denotes a maximum peak intensity measured on the specimen at 20.75° to 20.95° (2θ) by XRD analysis.
