Degradation mechanisms of silver nanowire electrodes under ultraviolet irradiation and heat treatment

Abstract We report the degradation mechanisms of the silver nanowire (Ag NW) electrodes that play a significantly important role in the stability of wearable and flexible devices. The degradation mechanisms behind the increase in the sheet resistances of Ag NW electrodes were clarified by investigat...
