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.

Process for forming an electrically conductive structure on a substrate

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 and semiconductor devices made therewith

A lead-free 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.

The invention relates to zinc-containing glass compositions useful in conductive pastes for silicon semiconductor devices and photovoltaic cells.

Glass compositions used in conductors for photovoltaic cells

Deposited thin-film dielectrics having columnar grains and high dielectric constants are formed on heat treated and polished metal foil. The sputtered dielectrics are annealed at low oxygen partial pressures.
