Abstract
The present invention relates to a composition for forming a solar cell electrode, comprising: silver (Ag) powder; a glass frit comprising silver (Ag) and tellurium (Te) elements; and an organic vehicle, wherein the glass frit has a mole ratio of 1:01 to 1:25 of Ag to Te. The solar cell electrode produced from the composition has excellent fill factor and conversion efficiency as contact resistance (Rc) and series resistance (Rs) are minimized.
