Abstract: Transparent electrodes are an important part of modern electronic evices and can be used in touch screens,LCDs,OLEDs,solar cells and other optoelectronic devices for their excellent electrical and optical properties. Various conductive materials were compared in the transparent conductive electrode,including metal oxides,new carbon materials,metal nanomaterials,composite materials and so on. The technology integrating composite materials with printing manufacturing will be the development trend of transparent electrode.
