All-solution processed micro/nano-wires as transparent conducting electrodes

We have developed an all-solution processed transparent conductive electrode with sheet resistance an order of magnitude smaller than conventional nanowire-based transparent conductors. This is achieved by integrating all-solution-produced microwires¹ with nanowires and electroplate welding. As a result, the advantages of these transparent conductors are indium-free, vacuum-free, lithographic-facility-free, metallic-mask-free, with small domain size, high specific conductivity and mechanical flexibility, thus making them an excellent replacement for ITO.
