It was found that the optical transmittance of the IAIA multilayer was significantly influenced by the top IZO layer thickness which was grown on identical AIA multilayers. However the sheet resistance of the IAIA multilayer was maintained between the range to Q square regardless of the top IZO thickness because the sheet resistance of the IAIA multilayer was mainly dependent on the thickness of the Ag layers. Notably the optimized IAIA multilayer had a constant resistance change AR R0 under repeated outer bending tests with a radius of 10 mm. The mechanical integrity of the R2R-sputtered IAIA multilayer indicated that hybridization of an IZO and Ag metal layer is a promising flexible electrode scheme for the next-generation flexible optoelectronics. Introduction Flexible transparent conducting oxide FTCO electrodes with superior flexibility have recently attracted much attention as key components in flexible displays photovol-taics and touch panels because device performances are critically dependent on optical electrical and mechanical properties of the FTCO 1-3 . In particular the FTCO electrode should have mechanical robustness against substrate bending without resultant changes in its optical and electrical properties. Until now amorphous indium tin oxide ITO electrodes have been widely employed as an FTCO material in flexible optoelectronic devices due to their high conductivity
