Abstract
A conductive paste composition contains a source of an electrically conductive metal, an alkaline-earth-metal boron tellurium oxide, 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 device substrate (e.g., by screen printing) and firing the paste to remove the organic vehicle and sinter the metal and establish electrical contact between it and the device.
