A paste composition contains an electrically conductive silver powder, one or more glass frits or fluxes, and a lithium compound dispersed in an organic medium. The paste is useful in forming an electrical contact on the front side of a solar cell device having an insulating layer. The lithium compound aids in establishing a low-resistance electrical contact between the front-side metallization and underlying semiconductor substrate during firing.

Conductive paste composition containing lithium, and articles made therefrom

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.

Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.
