Abstract

Official abstract text for this publication.

The present invention provides a process for using a thick-film conductive paste composition to form an electrode on a silicon semiconductor device, e.g, a photovoltaic cell, containing a lightly doped emitter. The thick-film paste comprises a source of an electrically conductive metal and a Pb—Te-based oxide dispersed in an organic medium. Also provided are devices made by the process and a photovoltaic cell comprising a lightly doped emitter and an electrode formed from the thick-film conductive paste composition.

First claim

Opening claim text (preview).

What is claimed is: 1. A process for forming a photovoltaic cell, the process comprising: (a) providing a junction-bearing silicon semiconductor substrate having a front-side surface and a back-side surface and comprising one or more insulating films disposed onto at least said front-side surface of said silicon semiconductor substrate and a lightly doped emitter at said front-side surface of said silicon semiconductor substrate; (b) applying a thick-film conductive paste compos…
