Conductive compositions containing rhodium and Pb-Te-O and their use in the manufacture of semiconductor devices

摘要

The present invention is directed to an electrically conductive composition comprising (a) an electrically conductive metal; (b) a Rh-containing component; (c) a Pb—Te—O; and (d) an organic medium; wherein the electrically conductive metal, the Rh-containing compound, and the Pb—Te—O are dispersed in the organic medium. The present invention is further directed to an electrode formed from the composition and a semiconductor device and, in particular, a solar cell comprising such an electrode. Also provided is a process for forming such an electrode. The electrodes provide good adhesion and good electrical performance.
