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

“…[1][2][3][4][5][6][7][8][9] A power conversion efficiency (PCE) of 22.1% has been certified on single-junction perovskite solar cells (PSCs), almost comparable to that of state-of-the-art crystalline silicon solar cells. [10] Besides the pursuit of an even higher PCE by enhancing perovskite film quality, [11][12][13][14][15] optimizing the device another key factor. [24] For example, the most widely investigated methylammonium (CH 3 NH 3 + or MA) lead iodide (MAPbI 3 ) is reported to undergo a phase transition at 54-57 °C [30,31] and degrade at temperature over 85 °C, [32] suggesting its poor thermal stability.…”

Mixed cation hybrid perovskites such as Cs [16][17][18] and adjusting the composition of perovskite films, [19][20][21][22] research efforts are also urgently needed to increase the scalability of research findings obtained in research labs and make this technology amenable for industry. There are two main challenges we are still facing.(I) The first is the stability challenge. At present stability of PSCs is still poorer than inorganic semiconductor based solar cells, foe example, crystalline silicon solar cells and thin film copper indium gallium selenide (CIGS) solar cells. [10,[23][24][25] To overcome the instability issue, external protections (e.g., perovskite surface functionalization, [26] utilization of chemically inert electron transport materials, hole transport materials and top electrode, deposition of additional protection layer, etc.) have been attempted. [27][28][29] Stability of the perovskite layer itself is Large-Area Perovskite Solar Modules

“…The reduction of charge recombination in bulk film requires high quality perovskite film with full surface coverage [26][27][28], large crystal size [15,29,30] and low defect density [31][32][33]. The post-treatment using a strong Lewis base is a very effective method to improve the quality of lead halide perovskite films [34][35][36][37][38][39][40][41][42]. In 2014, Zhao et al [34] first found a room-temperature phase transformation of CH 3 NH 3 PbI 3 induced by ammonia.…”

Abstract:The morphology control of CH 3 NH 3 PbI 3 (MAPbI 3 ) thin-film is crucial for the high-efficiency perovskite solar cells, especially for their planar structure devices. Here, a feasible and effective post-treatment method is presented to improve the quality of MAPbI 3 films by using methylamine (CH 3 NH 2 ) vapor. This post-treatment process is studied thoroughly, and the perovskite films with smooth surface, high preferential growth orientation and large crystals are obtained after 10 s treatment in MA atmosphere. It enhances the light absorption, and increases the recombination lifetime. Ultimately, the power conversion efficiency (PCE) of 15.3% for the FTO/TiO 2 /MAPbI 3 /spiro-OMeTAD/Ag planar architecture solar cells is achieved in combination with this post-treatment method. It represents a 40% improvement in PCE compared to the best control cell. Moreover, the whole post-treatment process is simple and cheap, which only requires some CH 3 NH 2 solution in absolute ethanol. It is beneficial to control the reaction rate by changing the volume of the solution. Therefore, we are convinced that the post-treatment method is a valid and essential approach for the fabrication of high-efficiency perovskite solar cells.
