Abstract: A new type of charge transport layer based on organometal halide perovskite for highly efficient organic light emitting diodes (OLEDs) is demonstrated. By solution processing of halide perovskite precursors, smooth essentially pure perovskite thin films may be prepared with high transparency and conductivity. Solution processed multilayer OLED with this perovskite-based hole transport layer outperforms a device with a PEDOT:PSS layer.
