1. A paste composition for an electrode of a solar cell comprising:
a conductive powder; an organic vehicle; and a glass frit composite; wherein the glass frit composite includes a first glass frit having a first glass transition temperature and a second glass frit having a second glass transition temperature lower than the first glass transition temperature, both the first glass transition temperature and the second glass transition temperature being lower than 450° C.; wherein the second glass transition temperature is lower than the first glass transition temperature within a range of 10° C. to about 50° C.; wherein the first glass frit acts to assist sintering by widening a sintering temperature range of the second glass frit; wherein the glass frit composite comprises about 5 to 30 parts by weight of the first glass frit per 100 parts by weight of the glass frit composite; and wherein the glass frit composite correspondingly comprises about 95 to 70 parts by weight of the second glass frit per 100 parts by weight of the glass frit composite.
