Silver nanowire based flexible electrodes with improved properties: High conductivity, transparency, adhesion and low haze

• Films exhibited low sheet resistance and optical properties with Rs ≤ 30 Ω/□ and T ≥ 90%.
• We decreased haze to 2% by controlling AgNWs length, diameter, and concentration.
• We achieved good adhesion for AgNWs on PET film.
• There is no significant change in resistance in the bending angle from 0° to 180°, and on twisting.

Recent work has been focusing on solution processable transparent electrodes for various applications including solar cells and displays. As well as, the research aims majorly at silver nanowires (AgNWs) to replace ITO. We enhance the transparent electrode performance as a function of optical and mechanical properties with low sheet resistance, by controlling the AgNWs accept ratios, ink composition, and processing conditions. The nanowire network of transparent films agrees with the 2D percolation law. The film transmittance values at 550 nm are coping with a reference ITO film. Sheet resistance and haze values are suitable for flexible electronic applications. We fabricate transparent flexible film using a low-cost processing technique.

This graphical abstract illustrates the schematic representation of the main drawbacks and rectifications for AgNWs based transparent electrodes.Figure optionsDownload as PowerPoint slide
