N2 - In this work, we present an alternative method for the spray coating of silver nanowire contact electrodes byemploying a mixture of short and long nanowires. Mixed silver nanowires are found to give improved opticalproperties with 2–5% higher transparency for the same sheet resistance of 25 Ω sq−1compared to silvernanowires prepared with a single geometry. The figure of merit for the 25 Ω sq−1sheet resistance electrode isfound 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 belower for mixed-composition silver nanowire electrodes(Rq = 3–4 nm)compared to individual parent fixeddimension-typesilver nanowire electrodes(Rq = 6–8 nm)
