Here, to realize flexible transparent electrode, we developed a highly conductive hybrid transparent electrode based on MXene nanosheet films and Ag nanowireds (AgNWs), which synergistically combines the advantageous characteristics of each material. MXene/AgNW/colorless polyimide (cPI) is fabricated by utilizing reverse sequential process and exhibits higher transmittance at 550 nm to 79% and lower sheet resistance (13.08 ohm/sq) compared with the MXene/cPI electrode (59% @ 550 nm, 113.6 ohm/sq). Flexible organic photovoltaic cells were fabricated using MXene/AgNW/cPI hybrid electrode, which obtain higher power conversion efficiency of 10.3% compared with 6.70% of the corresponding MXene/cPI electrode. Our results provides the great potential of Ti3C2-based MXene hybrid electrode as a flexible transparent electrode, paving the way for diverse and wider range of applications.
