Abstract

A composition for solar cell electrodes includes silver powder, a glass frit, and an organic vehicle. The glass frit includes a first glass frit and a second glass frit. The first glass frit includes tellurium (Te) and silver (Ag) in a molar ratio (Te:Ag) of about 75:1 to about 1:25. The second glass frit includes a lead-tellurium-oxide (Pb—Te—O)-based glass frit or a bismuth-tellurium-oxide (Bi—Te—O)-based glass frit and is free from silver (Ag).
