Zusammenfassung:Formulations and methods of making solar cells 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 boron source, 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 content of boron is about 0.05 to about 20 wt% of the mixture.
