Abstract
The paste composition of the instant invention consists of silver powder, glass frit, Bi2O3, metal additives and an organic medium. The present invention is further directed to an electrode formed from the paste composition and a semiconductor device and, in particular, a soar cell comprising such an electrode. The paste compositions provide a solderable electrode, particularly useful for forming solar cell back side buss bars on an aluminum layer that covers the entire back side surface of the solar cell.
