摘要:
Paste compositions, methods of making a paste composition, solar cells, and methods of making a solar cell contact are disclosed. The paste composition can include a conductive metal component, a glass component, and a vehicle. The glass component can include SiO2 at about 3 mole % or more and about 65 mole % or less of the glass component and one or more transition metal oxides at about 0.1 mole % or more and about 25 mole % or less of the glass component. The metal of the transition metal oxide is selected from the group consisting of Mn, Fe, Co, Ni, Cu, Ti, V, Cr, W, Nb, Ta, Hf, Mo, Zr, Rh, Ru, Pd, and Pt.

Paste compositions, methods of making a paste composition, and methods of making a solar cell contact are disclosed. The paste composition can contain silver, a glass frit, a metal additive and an organic vehicle system. The metal additive is at least one selected from the group consisting of yttrium, an organo-vanadium compound, organo-antimony compound, organo-phosphorus compound, and an organo-yttrium compound. The paste can be used for making a solar cell contact.
