Abstract

Transparent conductive electrodes are essential components of modern optoelectronic devices that offer high visible transmittance and low electrical resistance. As next-generation electronic devices, such as displays, flexible electronics, and wearable devices, continue to evolve, the demand for transparent electrodes with excellent mechanical flexibility and thermal stability has grown significantly. In this study, we demonstrated high-performance transparent electrodes with AZO/AgNW/AZO multilayer structures on PET substrates and evaluated their potential for use in flexible and transparent photovoltaic devices. The combination of the superior flexibility and thermal stability of AZO with the excellent electrical conductivity of AgNWs enabled the development of highly durable electrodes. Bending and heating tests confirmed that the AZO layers protected the AgNW networks, maintaining a stable sheet resistance with less than 5.5% increase after 1000 bending cycles. Furthermore, the structures exhibited robust thermal stability, maintaining a sheet resistance of 12.9 Ω/□ at 210℃. These results indicate that the AZO/AgNW/AZO multilayer electrodes are highly durable and are suitable for flexible devices and high-durability applications. This suggests the potential of AZO/AgNW/AZO structures as transparent electrodes for flexible electronics and energy devices.
