COMPOSITION FOR FORMING SOLAR CELL ELECTRODE AND ELECTRODE PRODUCED FROM SAME

摘要

The present invention relates to a composition for forming a solar cell electrode, comprising: silver powder; a bismuth oxide - tellurium oxide - tungsten oxide - zinc oxide - based glass frit; and an organic vehicle, wherein the glass frit comprises: about 40 wt% to about 60 wt% of bismuth oxide; about 0.25 wt% to about 15 wt% of tellurium oxide; about 10 wt% to about 20 wt% of tungsten oxide; and about 2 wt% to about 20 wt% of zinc oxide. The solar cell electrode produced from the composition for forming a solar cell electrode demonstrates excellent adhesion strength with a ribbon, and excellent conversion efficiency due to minimized series resistance (Rs).
