Metal‐microstructure based flexible transparent electrodes and their applications in electronic devices

Abstract Novel flexible transparent electrodes (FTEs) based on metal nanoparticles/nanowires (NWs), carbon nanotubes, graphene and conductive polymers play important roles in the development of flexible and even wearable electronic devices. Among them, the metal‐nanostructure‐based FTEs present high mechanical flexibility, excellent optical/electrical properties, and low cost, so they are attracting considerable attention in recent years. In this review, we will summarize the recent progress in metal‐nanostructure FTEs, including the metal NWs, ultrathin metals, metals mesh, and composite electrodes. Moreover, we will also systematically introduce their applications in flexible electronic devices such as organic light‐emitting diodes, supercapacitors, and solar cells.
