Optoelectronic devices such as organic (polymer) light emitting diodes (OLEDs and PLEDs), quantum dot solar cells (QDSCs) and organic photovoltaic (OPVs) have attracted significant attention as the next-generation flexible electronic devices (FEDs) that can enhance productivity by continuous processing. For high-efficiency FEDs, it is necessary to enhance its chemical and mechanical stability. In general, ITO (indium tin oxide) is the most common choice for a transparent conducting electrode (TCE) material, owing to its advantages of low resistivity and high transparency in the visible wavelength region. However, ITO has major drawbacks with respect to its costs and mechanical properties, generating cracks and fractures at low strains (2–3%). In this study, the IZTO electrode was manufactured to reduce the indium content than that used for ITO. The fabricated flexible PLEDs and OPVs showed comparable performance, compare to ITO glass based devices, with 4.0 mm of outer bending radius. |
