Abstract

A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes a silver (Ag) powder; a glass frit containing about 0.1 mole % to about 50 mole % of elemental silver; and an organic vehicle, wherein the elemental silver derives from a silver halide (Ag—X). The composition introduces a glass frit including a silver halide to enhance contact efficiency between electrodes and a silicon wafer, and solar cell electrodes prepared from the composition have minimized contact resistance (Rc), specific contact resistivity, and serial resistance (Rs), thereby exhibiting excellent conversion efficiency.
