Abstract: Provided herein are ink compositions with improved conductivity. The improved conductivity is attributable to the addition of organohalogen compounds to the composition.

Abstract: Solar cell conductor formulations made are from two silver powders having different particle size distributions, an aluminum powder, and two frit glass compositions having softening points in the range of 250-700° C. and whose softening points differ by at least 10° C.

Abstract: Paste compositions, methods of making a paste composition, photovoltaic cells, and methods of making a photovoltaic cell contact are disclosed. The paste composition can include a conductive metal component such as aluminum, phosphate glass, phosphorus compounds such as alky! phosphate, and a vehicle. The contact can be formed on a passivation layer on a silicon wafer by applying the paste on the passivation layer and firing the paste. During firing, the metal component can fire through the passivation layer, thereby electrically contacting the silicon substrate.

Abstract: Paste compositions, methods of making a paste composition, and methods of making a solar cell contact are disclosed. The paste composition can contain a nickel intermetallic compound such as nickel silicide, nickely boride or nickel phosphide, a glass frit, a metal additive and an organic vehicle system. The paste can be used for making a solar cell contact.

Abstract: This invention relates an aluminum conductor paste formulation and its method of application on rear side passivated locally opened vias; dot or line geometry or combination thereof employing laser ablation or chemical etching methods. Such Back Surface Passivated Si-solar cells include dielectric layers of Al203, SiNx, Si02, SiC, ?-Si, Si02/SiNx, Al203/SiNx, Si02/Al203/SiNx. The Al-conductor paste of this invention achieves; (i) non-degradation of passivation stack, (ii) defect free surfaces and void free vias, (iii) a strong and uniform Back Surface Field (BSF) layer within dot vias and line vias.
