Abstract: Provided herein are perovskite-polymer films, methods of forming polymer-perovskite films, and devices including polymer-perovskite films. The polymer-perovskite films may include a plurality of methylammonium lead chloride (CH3NH3PbCl3) nanopillar crystals embedded in a polymer matrix. The devices can be optoelectronic devices, such as light emitting diodes, which include polymer-perovskite films. The polymer-perovskite films of the devices can be hole transport layers in the devices. The methods of making films may include spin casting a precursor solution followed by thermal annealing.

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.
