Currently, poly(3,4-ehtylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is one of most attracting conductive polymer for optoelectronic devices as hole transport layer (HTL) due to its relatively high dipole formation and hole transport properties. However, PSS species in PEDOT:PSS, which has insulation property, cause the deteriorating conductance. Moreover, since PEDOT:PSS shows high surface energy, the morphology of organic-based upper layer can be adversely influenced. Under this consideration, introducing various conductive nano-particles into the PEDOT:PSS was studied. However, much research show little enhancement of conductance and poor stability. Herein, we incorporate the surface-functionalized nano MXene into PEDOT:PSS, which contribute to enhancing conductance and tuning intra-molecular property. Because MXene has the high metallic conductance, it can be expected to improve charge conductance of HTL. Moreover, controllable properties of that allow surface functional groups to be tuned for advancing intra-molecular properties. This work presents opportunities to design HTL candidate by manipulating morphology of MXene. |
