In this work, we present an alternative method for the spray coating of silver nanowire contact electrodes by
employing a mixture of short and long nanowires. Mixed silver nanowires are found to give improved optical
properties with 2–5% higher transparency for the same sheet resistance of 25 Ω sq−1
compared to silver
nanowires prepared with a single geometry. The figure of merit for the 25 Ω sq−1
sheet resistance electrode is
found to be highest for the mixed-composition AgNWs-M1 (mixture of AgNWs-30L and AgNWs-60S)electrodes.
The average root mean square surface roughness(Rq) parameter by white light interferometry is found to be
lower for mixed-composition silver nanowire electrodes(Rq = 3–4 nm)compared to individual parent fixeddimension-type
silver nanowire electrodes(Rq = 6–8 nm)
