Abstract
Transparent conductors including a silver layer with high transparency and low sheet resistance are described. In some examples, the silver layer can be located between two transparent conductive oxide layers. The transparent conductor can further include additional transparent conductive oxide layers, optical layers, and/or additional conductive layers (e.g., layers including ITO or another fully or partially transparent conductive material), for example. In some examples, transparent conductors including a silver layer can be included in a touch screen device. For example, one or more shielding layers or one or more touch electrodes can include transparent conductors with a silver layer. In some examples, the silver layer can improve transparency, sheet resistance, and/or infrared reflection characteristics of the transparent conductor.
