Strong Quantum Confinement and Fast Photoemission Activation in CH3NH3PbI3 Perovskite Nanocrystals Grown within Periodically Mesostructured Films
In this Communication, a synthetic route is demonstrated to obtain stabilized MAPbI3nanocrystals embedded in thin metal oxide films that display well-defined and adjustable quantum confinement effects over a wide range of 0.34 eV. Mesostructured TiO2 and SiO2 films...
Optical analysis of CH3NH3SnxPb1−xI3 absorbers: a roadmap for perovskite-on-perovskite tandem solar cells
Organic–inorganic perovskite structures in which lead is substituted by tin are exceptional candidates for broadband light absorption. Herein we present a thorough analysis of the optical properties of CH3NH3SnxPb1−xI3films, providing the field with definitive...
Gold promoted Cu/ZnO/Al2O3 catalyst prepared from hydrotalcite precursors: Advanced materials for the WGS reaction
Outstanding catalysts for the water was shift reaction are reported in this work. The combination of gold nanoparticles with Cu/ZnO/Al2O3 prepared from hydrotalcite-like precursors leads to very promising systems for pure hydrogen production. Full CO conversion is...
Unbroken Perovskite: Interplay of Morphology, Electro-optical Properties, and Ionic Movement
Hybrid organic–inorganic perovskite materials have risen up as leading components for light harvesting applications. However, to date many questions are still open concerning the operation of perovskite solar cells (PSCs). A systematic analysis of the interplay among...
