Zusammenfassung:Formulations and methods of making solar cell contacts and cells therewith are disclosed. In general, the invention provides a solar cell comprising a contact made from a mixture wherein, prior to firing, the mixture comprises at least one aluminum source, at least one source of a metal including one or more of boron, titanium, nickel, tin, gallium zinc, indium, and copper, and about 0.1 to about 10 wt % of a glass component. Within the mixture, the overall content of aluminum is about 50 wt % to about 85 wt % of the mixture, and the overall combined content of boron, nickel, tin, silver, gallium, zinc, indium, copper, is about 0.05 to about 40 wt % of the mixture.
