Abstract
A composition for solar cell electrodes and electrodes fabricated using the same. The composition includes a silver (Ag) powder; a first glass frit containing PbO and a second glass frit containing VOand TeO; and an organic vehicle. The composition includes two types of glass frits on PbO and VOTeO, respectively, thereby minimizing contact resistance and adverse influence on a p-n junction of silicon solar cells.
