COMPOSITION FOR FORMING SOLAR CELL ELECTRODE AND ELECTRODE PREPARED USING THE SAME

摘要

The present invention relates to a composition for forming a solar cell electrode, wherein the composition comprises; silver powder; a bismuth oxide-tellurium oxide-tungsten oxide-based glass frit; and an organic vehicle. The glass frit comprises: 40 to 60 wt% of bismuth oxide which is a first metal oxide; 0.25 to 15 wt% of tellurium oxide which is a second metal oxide; 10 to 20 wt% of tungsten oxide which is a third metal oxide; and 15 to 25 wt% of a fourth metal oxide which is different from the first to third metal oxides. A solar cell electrode produced through the composition for forming a solar cell electrode has excellent adhesion strength with a ribbon, and series resistance (Rs) is minimized so that conversion efficiency is excellent.
