Anti-solvent engineering enables efficient ambient-processed halide perovskite solar cells
Ambient solution-processed halide perovskite thin films are susceptible to oxygen and moisture. Composition and morphology control of the films via anti-solvents treatment, i.e., DCB, EtOH, and CB affect their crystallization and solar cell performance.

Chemically driven dimensionality modulation of hybrid tin(II) halide perovskite microcrystals
Synthesis conditions determine the dimensionality of TEA–Sn perovskites from low emissive 2D structures to highly luminescent 0D structures. Br-derivatives can be tuned to form 0D and 2D structures, 0D Cl and 2D I-based cannot be dimensional tuned.

Reactive spin coating based on real-time in situ feedback for improved control of perovskite thin film fabrication
This work presents a novel perovskite thin film fabrication approach based on an optical in situ spectroscopy setup and a live closed-loop feedback system to improve the reproducibility of the layer properties independent of external parameters.

Ionic liquid-regulated PbI2 layers and defect passivation for efficient perovskite solar cells
In this work, formamidine acetate (FAAc) was introduced in the two-step method to regulate perovskite crystallization and passivate defects, which resulted in achieving the PCE of device exceeding 24% with notable improvements in stability.

Thermal degradation in methylammonium–formamidinium–guanidinium lead iodide perovskites
Thermal degradation experiments in GAxFAyMA1−x−yPbI3 perovskites show that mixed compositions are generally more stable, but not always. Large GA+ cations may decrease the stability and even change the order of the degradation kinetics.

About this collection
A perovskite name is applied to the class of compounds which have the same type of crystal structure as CaTiO3 discovered in Ural mountains in 1839 by Gustav Rose. The ABX3 perovskite structure can accommodate a wide variety of different cations and anions. Depending on the chemical composition it can exhibit extremely different properties such like colossal magnetoresistance, ferroelectricity, superconductivity, light absorption, charge ordering, spin dependent transport, high thermopower, to name a few. Thanks to that, a variety of different devices can be constructed using this crystal structure.
This Journal of Materials Chemistry C themed collection brings together manuscripts related to all aspects of the cutting-edge innovations in the development of organic, inorganic and/or hybrid perovskite materials and devices with the focus on potential applications in memories, solar cells, sensors, catalyst electrodes and superconducting ceramic materials.
