Abstract
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.
