An electrical conductor structure comprises a substrate and an electrical conductor disposed on or in the substrate. The electrical conductor comprises a first layer and a second layer disposed on a side of the first layer opposite the substrate. The first layer comprises a first electrical conductor that forms a non-conductive layer on a surface of the first electrical conductor when exposed to air and the second layer comprising a second electrical conductor that does not form a non-conductive layer on a surface of the second electrical conductor when exposed to air. A component comprises a connection post that is electrically connected to the second layer and the electrical conductor. The first and second layers can be inorganic. The first layer can comprise a metal such as aluminum and the second layer can comprise an electrically conductive metal oxide such as indium tin oxide.
An electrical conductor, comprising a first layer and a second layer, the first layer comprising a metallic conductor and the second layer comprising three sublayers, a first sublayer comprising indium tin oxide (ITO) disposed on the first layer, a second sublayer comprising chromium disposed on the first sublayer, and a third sublayer comprising ITO disposed on the second sublayer such that the second sublayer is disposed between the first sublayer and the third sublayer.
An electrical conductor structure, comprising an exposed electrical conductor disposed on or in a substrate, wherein the electrical conductor comprises an opaque material having a transparency to visible light of less than 50% disposed between continuous layers of electrically conductive metal oxide.
An electrical conductor structure, comprising an electrical conductor disposed on or in a substrate, wherein the electrical conductor comprises an opaque material having a transparency to visible light of less than 50% disposed between layers of electrically conductive metal oxide,
An electrical conductor structure, comprising an electrical conductor disposed on or in a substrate and a component comprising a connection post,
