Optoelectronics: High-Performance Planar Perovskite Optoelectronic Devices: A Morphological and Interfacial Control by Polar Solvent Treatment (Adv. Mater. 23/2015)

On page 3492, S. U. Cho, M. H. Song, and co-workers demonstrate highly efficient planar perovskite light-emitting diodes (LEDs) and solar cells by applying amine-based solvent treatment on compact TiO2 and optimizing the morphology of the perovskite layers. This technique can be utilized as a simple and effective route to achieving high performance with a uniform morphology of the perovskite film.
