Abstract

Abstract: Silver nanowires (AgNWs) based electrode are the potential candidates to replace expensive ITO electrodes in the next generation of flexible electronics. Herein, AgNWs of ∼1000 aspect ratio were synthesised by using simple and cost-effective salt mediated polyol synthesis method. The AgNWs based transparent conducting electrodes (TCEs) have demonstrated the transparency and sheet resistance of 81% and 20 Ω/sq. The effect of AgNO3 injection rate, PVP/AgNO3 molar ratio, and NaCl/KBr ratio on the AgNWs morphology was extensively studied and optimized to 0.2 mL/min, 4.5:1 and 3.8:1, respectively. The effect of post annealing on TCE has also been studied and optimized to 150 °C.
