A composition for solar cell electrodes includes a silver (Ag) powder, a glass frit containing silver (Ag), tellurium (Te) and zinc (Zn), and an organic vehicle, wherein the glass frit has a mole ratio of Ag to Te ranging from about 1:0.1 to about 1:50 and a mole ratio of Ag to Zn ranging from about 1:0.1 to about 1:40.

Composition for solar cell electrodes and electrode fabricated using the same

Example embodiments relate to a composition for forming a solar cell electrode, and a solar cell electrode prepared using the composition. The composition for forming a solar cell electrode includes a silver (Ag) powder, a glass frit, and an organic vehicle, wherein the glass frit includes silver (Ag); tellurium (Te); and at least one selected from the group of lithium (Li), sodium (Na), and potassium (K), a molar ratio of the silver (Ag):the tellurium (Te) included in the glass frit is in a range of about 1:0.1 to about 1:50, and a molar ratio of the silver (Ag):lithium (Li), sodium (Na) or potassium (K) is in a range of about 1:0.01 to about 1:10. The solar cell electrode prepared using the composition has excellent fill factor and conversion efficiency due to minimized contact resistance (Rc) and series resistance (Rs).

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