Transparent conductive thin films are widely used in technologies like solar cells, light-emitting diodes, and display technologies. The fabrication of transparent conductive films is currently realized with thin films of transparent conductive oxides (TCOs), and in particular indium tin oxide (ITO). The as-made ITO transparent conductors suffer from limitations like costly fabrication process and brittleness. The use of solution-processable nanomaterials, and especially metallic nanowires, appears as a promising alternative since it affords a large area, low-cost deposition method with high performances.This thesis report that by optimizing synthesis methods and printing methods, flexible electrodes demonstrating excellent opto-electronic ...
