Abstract
The present invention relates to a composition for preparing solar cell electrodes including: a silver (Ag) powder; a glass frit containing about 0.1 mole % to about 50 mole % of elemental silver; and an organic vehicle, the composition introduces a glass frit including a silver cyanate or a silver nitrate to enhance contact efficiency between an electrode and a wafer, and solar cell electrodes prepared from the composition have minimized contact resistance (Rc) and serial resistance (Rs), thereby exhibiting excellent conversion efficiency.
