The present invention provides a thick-film paste for printing the front-side of a solar cell device having one or more insulating layers. The thick-film paste comprises an electrically conductive metal, and a lead-tellurium-oxide dispersed in an organic medium.

Thick-film pastes containing lead- and tellurium-oxides, and their use in the manufacture of semiconductor devices

A conductive paste composition contains a source of an electrically conductive metal, a first oxide component, a second, non-oxide, magnesium-containing component, 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 substrate.

Devices, methods, and systems are described for thick-film paste with multiple discrete frits. The paste may be applied to contacting crystalline silicon solar cell emitter surfaces. Each frit contains both lead and tellurium. The described multiple discrete frit paste has superior solar cell performance compared with single frit pastes made from the individual discrete frits that make-up the multiple frit paste.

A conductive paste composition contains a source of an electrically conductive metal, a Ti&#x2014;Te&#x2014;Li 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 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.

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.
