Abstract
The present invention provides a thick-film paste composition comprising an electrically conductive metal and an oxide composition dispersed in an organic medium. The paste composition is printed on the front side of a solar cell device having one or more insulating layers and fired to form an electrode, and is suitable for devices having both highly and lightly doped emitter structures.
