Patent ID: 10475548

Abstract:
Electrically conductive, thin, smooth films are provided that comprise silver (Ag) and a conductive metal, such as aluminum (Al), titanium (Ti), nickel (Ni), chromium (Cr), gold (Au), magnesium (Mg), tantalum (Ta), germanium (Ge) or combinations thereof. In other alternative variations, electrically conductive, thin, smooth films are provided that comprise gold (Au) or copper (Cu) and a conductive metal, such as aluminum (Al), titanium (Ti), nickel (Ni), chromium (Cr), gold (Au), magnesium (Mg), tantalum (Ta), germanium (Ge) or combinations thereof. Such materials have excellent electrical conductivity, may be ultra-thin, flexible, transparent, and have low optical loss. Assemblies incorporating such films and methods of making the films are also provided. The assemblies may be used in photovoltaic and light emitting devices with high power conversion efficiencies or optical meta-materials that exhibit high transmittance and homogeneous response, among others.
