Spray deposition of Silver Nanowire transparent conductive networks

We investigate Silver Nanowire (AgNW) networks, deposited by spray coating, on a flexible plastic substrate, for application as transparent electrodes for Indium Tin Oxide (ITO) replacement. We demonstrate that the network performance is controlled by the size distribution of the droplets impinging the substrate. Droplet size distribution can be controlled by tuning the spray pressure. Under the most favorable conditions, we achieve networks with typical transmittance T~90% and sheet resistance Rs~50Ω/□, and Rs~1kΩ/□ at T~94%.
