The present invention provides a method of producing a layer of crystalline material, the crystalline material comprises a perovskite or six halogenated metal salt, the method comprising: (i) exposing the substrate containing the first front in the first chamber compound vapor to produce layers of ...
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, ...
PEROVSKITEGRAZING incidenceX-ray scatteringSOLAR cellsThe 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 ...
Organic spacers are classified into the box of “2D perovskite” and “non-2D perovskite” based on whether the 2D perovskite structure is formed. Full size image To reduce experimental cost in this work, the same experimental conditions such as inorganic precursors, solvent, concentration, and t...
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 rapidly produce silver nanoparticles with the desire...
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...
Two-step spray method is developed to deposit perovskite film in ambient conditions.Perovskite film deposited by this method has high crystalline quality and few defects.Perovskite solar cells with efficiency as high as 16% were constructed by this method.Large-area (1脳1cm2) cell with efficiency...
The CsPbBr3 perovskite was then prepared on the ZrO2 surface through a two-step method. First, the PbBr2 precursor solution was drop-cast onto the ZrO2 surface, followed by annealing to obtain a PbBr2 thin film. Subsequently, immersion in a CsBr solution for a certain period of time and ...
process, in the planar perovskite solar cell configuration, by replacing the solution-phase organic dipping step with an atmospheric pressure vapour-phase conversion, where the spincoated metal halide is annealed in an atmosphere of the sublimed organic component to convert it to the perovskite. This...
To overcome this shortcoming, we introduce a conjugated molecule, 3‐phenyl‐2‐propen‐1‐amine (PPA), into CsPbBr3 NCs through a two‐step surface ligand engineering process. Owing to excellent electrical conductivity of PPA, PPA‐capped CsPbBr3 NCs LEDs exhibit a maximum current efficiency of...
