Ionic liquids(ILs)have been widely applied in the one-step fabrication of perovskite with noticeable enhancement in the device performance.However,in-depth mechanism of ionic-liquid-assisted perovskite film formation is not well understood for also important two-step perovskite fabrication method,with ...
perovskitenucleation and growthA general approach to the formation of well-faceted nanoparticles is discussed and successfully applied to the production of several rare-earth scandates. Two steps were used, with higher temperatures first to nucleate the perovskite phase, followed by lower temperatures ...
Mixed 2D/3D perovskite films with self‐assembled quantum wells have significantly improved the performance of perovskite light emitting diodes (PeLEDs). In this work, such films are fabricated through a two‐step interdiffusion method that is widely employed in processing of perovskite solar cells, ...
The present invention provides a process for producing a layer of a crystalline material comprising a perovskite or a hexahalometallate, which process comprises: (i) exposing a subs
In materials science, the discovery of recipes that yield nanomaterials with defined optical properties is costly and time-consuming. In this study, we present a two-step framework for a machine learning-driven high-throughput microfluidic platform to ra

Flexible perovskite solar cells were prepared using two-step solution-processed SnO2 layers as electron-transport-material. The first layer was constructed by hydrothermal derived SnO2 nanoparticles, and the second layer was in-situ formed from hydrolysis and oxidization of SnCl2. It was observed that...
The addition of methylammonium chloride (MACl) significantly improves the performance and stability of perovskite fabricated by two-step processes. However, its role in crystallization dynamics has not been thoroughly studied. In this work, a comparison study is carried out using different additions of...
