Abstract
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.
