The invention discloses a slurry composition, which is composed of silver powder, glass frit, Bi 2 O 3 , metal additives and organic medium. The present invention also relates to electrodes formed from the paste composition and semiconductor devices, in particular solar cells comprising such electrodes. The paste composition provides a solderable electrode and is particularly useful for forming solar cell backside bus bars on an aluminum layer covering the entire backside surface of the solar cell. |
