Abstract

We investigated characteristics of Ti-doped In₂O₃ (TIO)/Ag nanowire (NW)/TIO films as potential transparent and flexible electrodes for flexible organic solar cells. Effective insertion of metallic Ag NW between TIO layers led to improvement of electrical and mechanical properties of sputtered TIO film. At optimized conditions, we achieved a flexible TIO/Ag NW/TIO multilayer with a low sheet resistance of 9.01 Ω/square and a high optical transmittance of 85.14%. In addition, the TIO/Ag NW/TIO multilayer electrode showed small inner and outer bending radius of 5 and 6.5 mm indicating good flexibility. This indicates that hybridization of sputtered TIO films and printed Ag NW network is a promising solution to solve critical problems of high resistance and brittle TIO film and Ag NW network with poor adhesion.
