Abstract
A conductive paste composition contains a source of an electrically conductive metal, a lead-tellurium-based oxide, a discrete oxide of an adhesion promoting element, and an organic vehicle. An article such as a high-efficiency photovoltaic cell is formed by a process of deposition of the paste composition on a semiconductor substrate (e.g., by screen printing) and firing the paste to remove the organic vehicle and sinter the metal and lead-tellurium-based oxide.
