제목 Interfacial Energy Barrier Control for Enhancing the Efficiency of Organic Optoelectronic Devices
초록 We present an interfacial energy barrier control using conjugated polyelectrolytes (CPEs) with different thicknesses and various ion densities under electric poling for highly efficient polymer light-emitting diodes (PLEDs) and solar cells (PSCs). With regard to the mechanism for interfacial energy level adjustment, the permanent spontaneous dipole model is suitable when the CPE film is thin (2 nm), whereas redistribution of the internal field by ion migration applies when the CPE film is thick (10 nm). The results of this study demonstrate that the interfacial energy level adjustment and charge injection/extraction can be finely modulated by using this series of CPEs bearing various ion densities and additional electric poling for PLED and PSC optimization.
