Metal halide perovskites have emerged as a rising star among various semiconductor materials in the past few years owing to their low cost, solution processability and fascinating combination of material properties, including tunable bandgap, high absorption coefficient, broad absorption spectrum, high charge carrier mobility and long charge diffusion length, which enable a broad range of photovoltaic and optoelectronic applications. Accompanied by the success in photovoltaic community that has witnessed a certified power conversion efficiency of 22.1% through a few years’ efforts, the rapid advancement is also achieved in the areas of light-emitting diodes, lasers, photodetectors, and solar-to-fuel energy conversion devices. Beyond the dominant format of polycrystalline perovskite thin films for solar cell applications, recent progress in metal halide perovskite crystals, ranging from nanocrystals, nanowires to macroscopic single-crystals, has spurred paramount scientific and industrial interests. Great research efforts have endeavored to develop new techniques for crystal growth, investigate the physical and chemical properties of the materials and explore their emerging applications. The perovskite single crystals, for instance, provide an excellent platform to characterize a range of materials’ properties that could not be achieved by studying polycrystalline thin films. Understanding the mechanism of the crystal growth provides insights for the better control of polycrystalline thin film quality in terms of crystal orientation and defect density, the key facts that restrict the solar cell performance. Perovskite nanocrystals and nanowires exhibit superior luminescent performance than their thin film counterparts, enabling potential applications like large area display. These exciting achievements call for a rationalization of the different forms of perovskite semiconductors beyond the widely used polycrystalline thin films. In the current Special Issue: “Metal Halide Perovskite Crystals: Growth Techniques, Properties and Emerging Applications”, we aim to provide a forum for the discussion and presentation of recent advances in the fields of research related to metal halide perovskite crystals. The potential topics of interest could be, but are not limited to:
- Growth techniques of metal halide perovskite single crystals, nanowire and nanocystals
- Mechanism of crystal growth
- Characterization of metal halide perovskite crystals
- Emerging applications of metal halide perovskite crystals
Scientists working in this broad field, and many other aspects related to perovskite crystals but not summarized here, are invited to present their work in this Special Issue. Full papers, communications, and reviews are all welcome.

Title: Enhancing Optical Pumped Organic- Inorganic Hybrid Perovskite Amplified Spontaneous Emission via Compound Surface Plasmon Resonance

Abstract: Organic- inorganic hybrid perovskite has been attracted attention as the gain medium in lasers. But achieving electrically driven lasing remains a significant challenge. Through the devices structure modification to enhance the optical pumped amplified spontaneous emission (ASE) is the key issue. In this report, gold nanoparticles (Au NPs) are doped into PEDOT: PSS in a slab waveguide device structure: Quartz/PEDOT: PSS (with or without Au NPs)/CH3NH3PbBr3/Air. As a result, the facile device structure shows a significant enhancement of ASE intensity. Through experiments and theoretical simulation, the enhancement of devices performance mainly originated from the compound surface plasmon resonance, including simultaneous near- and far- field effects, which both could increase the density of excited state and accelerate the radiative decay process. This method is very meaningful to the design and development in fabricating the high performance organic- inorganic hybrid perovskite lasers.

Abstract: Iodine was carried out as an additive to modify the interface between perovskite and spiro-OMeTAD hole transport layer. The oxidation ability of iodine significantly improved the efficiency of charge extraction for perovskite solar cells. It reveals that the Voc and FF of perovskite solar cells were improved significantly due to the dopant, mainly attributed to the benefits of interficial improvement. It was found that the performance of perovskite solar cells achieved to the best when the dopant of iodine was the same with spiro-OMeTAD in equivalent mole weight. Moreover, the long-term stability of the corresponding device was investigated.

Abstract: Witnessed by its appealing application in energy harvesting industry, metal halide perovskite solar cell is attracting increasing attention from various fields, for example, chemistry, materials, physics and energy related industry. While the energy conversion efficiency of perovskite solar cell is being renewed day by day from various research groups, the relationship between structure and property is still ambiguous, to some extent, and therefore becomes an urgent topic for its wide application in real environment. The fine structure characterization of perovskite thin films or crystals recently has been performed by varying techniques, such as XRD, synchrotron-based grazing incidence XRD and SAS, SEM, STM and so on. In this article, we will review the recent progress in monitoring the nanostructures and crystallization using such state-of-art approaches, shortly introduce the related work performed in our group, as well as the promising prospective.
