Abstract:Transparent electrodes are critical components of optoelectronic devices such as solar cells, organic light-emitting diodes, and displays. Most high-performance transparent conducting films at present are composed of sputtered metal oxides, which have limited flexibility because of its brittleness. Vacuum sputtering is also an expensive process and high energy consumption. Conductive networks based on solution-processed silver nanowire (Ag NW) have received substantial attentions because of its high conductivity, low-cost and easy-processingin recent years. However, most of reported conductive Ag NW networks were deposited without pattern, which need additional patterning procedures for practical applications. In this report, Ag NWs were gravure printed on PET film to form patterned conductive transparent electrodes. Different from inkjet printing, gravure printing can deposit suspensions containing 20 micron long Ag NWs very fast and effective. A series of Ag NW suspensions were formulated and various printing parameters were investigated in our printing experiments. Printed samples were characterized to explore the structure and morphology of films. It was found that Ag NW concentration and distribution play key roles in the optical transmission and electrical conductivity. Experimental result showed that with optimized parameters the transmission of 89% at sheet resistance of 200Ω /
