Fully Vapor-Deposited Heterostructured Light-Emitting Diode Based on Organo-Metal Halide Perovskite

The first example of an efficient, fully vapor-processed, perovskite-based electroluminescent device is reported. This innovative heterostructured device represents an important advancement of the technology, allowing for complete manufacture without breaking the vacuum, thus for a better control of charge transport and electroluminescent properties of the device constituents.
