Abstract
A conductive paste composition contains a source of an electrically conductive metal, a fusible material, a synthetic clay additive, and an optional etchant additive, dispersed in an organic medium. An article such as a photovoltaic cell is formed by a process having the steps of deposition of the paste composition on a semiconductor substrate by a process such as screen printing and firing the paste to remove the organic medium and sinter the metal and fusible material. The synthetic clay additive aids in establishing a low resistance electrical contact between the front side metallization and underlying semiconductor substrate during firing.
