Organo-lead halide perovskites are promising materials for the development of solar cells, solid-state lasers, light emitting diodes (LEDs), photodetectors, etc. Perovskites can easily be deposited from their precursor solutions into a thin film by solution-based processes [1]. Nevertheless, the prepared films possess defects which cause non-radiative recombination, current-voltage hysteresis and rapid degradation due to the low stability of the resulting devices [1].The efficiency of the functional devices descends dramatically when amorphous materials are implemented instead of highly crystalline ones. Therefore, it is challenging to optimize and up-scale the production of large-sized single crystals of perovskite materials. Here, we describe a novel and original approach to MAPbBr3, FAPbBr3, MAPbI2 and FAPbI2 lead halide perovskite single crystals preparation which consists in applying microwave radiation during the crystallization [1]. The facile microwave assisted method of preparation is highly reproducible, fully automated and in addition, it can be applied for various different perovskite structures. Simultaneously, this eco-friendly method is expected to be easily up-scalable because of its versatility and low energy consumption. We believe that this method will make preparation of single crystals, nanosystems, 2D systems and the final functional devices fabrication (like solar cells, LEDs, photodetectors, i. e.) more convenient and efficient.
