This study presents a highly transparent and conductive hybrid electrode for flexible optoelectronic devices, which is fabricated by a simple spray method. The hybrid electrode exhibits excellent performance, including high transmittance and low sheet resistance.
Flexible organic light emitting diodes (OLED) have attracted great attention in many applications. MXene based flexible transparent conductive films (TCFs) are the most promising next-generation electrodes for flexible electronics. Herein, the sandwich conductive structure of silver nanowires (AgNWs) network, new 2D nanosheets with excellent conductivity, hydrophilicity and mechanical flexibility and PEDOT:PSS contributes to a highly transparent and conductive hybrid electrode through a simple, scalable, low-cost spray method. The Ti3C2T (x) /AgNWs/PEDOT-PET film shows a low sheet resistance (<30 omega/sq) and high transmittance (>80%) at 550 nm. Flexible OLED with such hybrid anode has the maximum brightness, current efficiency and current density, as high as 10 040 cd m(-2), 3.7 cd A(-1) and 535.5 mA cm(-2), respectively. These results indicate that the novel Ti3C2T (x) /AgNWs/PEDOT-PET TCFs have a great potential for high-performance flexible optoelectronic devices.
