“…[28] The perovskite film quality, morphology and material properties are greatly influenced by this step provided that the precursor film is completely wet on a substrate. Although, interesting attempts to form perovskite crystal without thermal annealing were carried out in recent years, film quality and device performance of state of the art devices are still largely relying on this approach.…”

“…[28][29][30] Thermal treatment is the most widely used methods to convert solution-processed precursor films into perovskite crystalline phase while different processing parameters lead to the modification of surface coverages, crystal grain sizes and relevant material properties. Here, fine control of the crystalline nucleation and growth via additives, vapor treatment, solvent annealing and intermediate phase mediator is required to obtain high crystalline perovskite films.…”

Outstanding material properties of organic-inorganic hybrid perovskites have triggered a new research insight into the next-generation solar cells. Moreover, a wide range of controllable properties of hybrid perovskites particularly depending on crystal growth conditions enables versatile high performance optoelectronic devices such as light-emitting diodes, photodetectors and lasers beyond solar cells. This invited review article highlights recent progress of the crystallization strategies of organic-inorganic hybrid perovskites for effective light harvester or light emitter. In the first part, fundamental background on the perovskite crystalline structures and relevant optoelectronic properties such as optical band-gap, electron-hole behavior and energy band alignment are introduced. In the second part, detailed overview of the effective crystallization methods for perovskites, including thermal treatment, additives, solvent mediator, laser irradiation, nanostructure, crystal dimensionality and so on, is described to offer a comprehensive correlation among perovskite processing conditions, crystalline morphology and relevant device performances. Finally, future research direction is proposed to overcome current practical bottlenecks and move towards reliable high performance perovskite optoelectronic applications.3

“…[18,83] Recently, very thin perovskite wafers could be realized by confined growth within a microreactor created www.advancedsciencenews.com from two glass slides with appropriate spacers, paving the way for mass production of solution-processed wafers. [84] For further information on the growth control of perovskite films and single crystals by many different methods that could also be relevant to industry, we refer the reader to the recently published review by Chen et al [85] …”

following statement: These materials can be processed from solution and yet exhibit optoelectronic materials properties described in classic solid-state physics textbooks. This unprecedented combination has led to photovoltaic devices that can be processed at room temperature and achieve performance levels similar to industry giant polycrystalline silicon, from a starting point of 3.8% in 2009. [1][2][3][4] The first light-emitting electrochemical cells [5] and diodes [6][7][8] have also been introduced recently, leading to tunable light emission spectra and internal quantum efficiencies exceeding 15%.The road towards these achievements has been marked by a constant improvement of perovskite deposition techniques fueled by our increasing understanding of the crystallization processes. The choice of deposition technique, either from solution or vapor, and the composition and order in which precursor species are applied has a great influence on the crystallization kinetics. Here, one can distinguish one-step methods where the perovskite is formed from a precursor mixture dissolved in a common solution, and two-step methods where the inorganic compound is deposited first and transformed to the perovskite phase later by addition of the organic constituents. [9][10][11] Furthermore, many parameters during processing can have an effect on the crystallization mechanism and consequently on film morphology, such as the choice of solvents, concentrations and processing additives that are often not incorporated into the final product. [11][12][13] We discuss this aspect in Section 2, where we focus our attention on the most commonly employed solution-based techniques. Additionally, as for any new technology trying to displace an incumbent technology, higher efficiencies, lower costs, reproducibility, stability, and sustainability are paramount. In particular, reproducibility has been a major challenge in perovskite solar cells from the beginning: small variations in morphology, like crystal size, film roughness, and pinholes can have detrimental effects on photovoltaic performance. [14] On the other hand, current-voltage measurements often showed a hysteresis that is rarely seen in other photovoltaic technologies. [15] These topics are highlighted in Sections 3 and 4. Finally, in Section 5 we discuss the framework for market introduction, such as cost reduction by choosing low-cost charge transport layers, or how the lifetime of perovskite absorbers can be extended by the choice of materials composition.Hybrid metal halide perovskites have become one of the hottest topics in optoelectronic materials research in recent years. Not only have they surpassed everyone's expectations and achieved similar performance as tried and true polycrystalline silicon photovoltaic devices, but they are also finding applications in a variety of different fields, including lighting. The main advantages of hybrid metal halide perovskites are simple processability, compatible with large-scale solution processing such as roll-to-roll printing, a...

“…Currently, perovskite thin films have been under intensive investigation and most reported applications have focused on polycrystalline thin films. Accordingly, a lot of recent reviews regarding the progress in perovskites concentrate on their polycrystalline film form [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Although the study of perovskite single crystals is just in its early stage, it is highly desirable to investigate fundamentally intrinsic properties of perovskites due to their low trap density and absence of grain boundaries.…”
