A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes a silver (Ag) powder; a first glass frit containing PbO and a second glass frit containing VOand TeO; and an organic vehicle. The composition includes two types of glass frits on PbO and VOTeO, respectively, thereby minimizing contact resistance and adverse influence on a p-n junction of silicon solar cells.

Composition for forming solar cell electrode and electrode produced from same

A composition for solar cell electrodes includes a conductive powder, a glass frit, an organic vehicle, and a thixotropic agent, the composition satisfying each of Formulae 1 to 7 described herein. A solar cell electrode is produced from the composition. A method of manufacturing a solar cell includes printing the composition in a predetermined pattern over a front surface of a wafer, and firing the printed composition pattern to form at least electrode.

Composition for forming solar cell electrode, and electrode produced from composition

A glass frit includes at least three metal oxides selected from the group of lead oxide, silicon oxide, tellurium oxide, bismuth oxide, zinc oxide, and tungsten oxide, wherein the glass frit exhibits a phase transition peak in the range of about 300&#xb0; C. to about 600&#xb0; C. on a cooling curve obtained via an TG-DTA analysis while a mixture of the glass frit and silver powder, obtained by mixing the glass frit with the silver powder in a weight ratio of 1:1, is cooled at a cooling rate of 10&#xb0; C./min, after heating the mixture to 850&#xb0; C. at a heating rate of 20&#xb0; C./min and held there for a wait-time of 10 minutes.
