Alternative transparent conducting electrode for flexible optoelectronics

Abstract

Transparent conducting electrode for the organic optoelectronic devices are gathering a tremendous amount of interest. Most of the conducting electrodes like Indium Tin Oxide (ITO) are fabricated at high temperature. In recent years, flexible transparent electrodes fabricated with silver nanowires (AgNWs) extensively studied. This is a promising alternative to ITO film in an optoelectronic application. ITO may present good conductivity and transparency for the optoelectronic device but, due to its mechanical non-robust nature, it is hard to fabricate, process and use on flexible substrates like poly (ethylene terephthalate) (PET) and epoxy. These solution process methods are also important due to ease of process and large area coating without losing its electronic property. In this work alternative conducting electrodes are prepared by solution process and effect of the silver nanowire on sheet resistance has been studied. Optical and mechanical properties correlated to electronic properties are also evaluated.
