Thermal properties of silver nanowire networks

Silver nanowire (AgNW) networks have recently been the focus of intense research due to their potential use as transparent electrodes in solar cells, flat panel displays or transparent heaters. Metallic nanowire networks can be deposited using low-cost and scalable deposition techniques on flexible substrates. For improving the transport properties (thermal and electrical) and optical transmittance in the visible range, an optimum nanowire density should be considered. In the present contribution we investigate the thermal behaviour of AgNW networks based on two aspects. The first one shows that a thermal annealing can drastically improve transport properties. The second approach investigates the physical properties of the network when used to generate heat. Experimental observation shows that AgNW networks exhibit the properties of a very efficient transparent heater, making them appropriate for future uses compatible with large area and flexible display technology. A comprehensive understanding of the thermal properties of this promising transparent nanostructured network will be presented
