“…By fine-tuning the parameters of the TE system, such as the deposition rate, temperature, and pressure, it is possible to obtain desired results of variables such as thickness, uniformity, bond strength, stress, grain structure, and optical or electrical properties. Although TE has been a common deposition method for several decades, the growth of high-quality metal halide perovskite thin films through TE has only recently been explored. − The technique has shown promising results for the preparation of high-quality metal halide perovskite thin films with excellent crystalline quality and uniformity, making it a promising candidate for the scalable production of metal halide perovskite devices …”

Epitaxial growth technology has garnered widespread attention in the field of perovskite solar cells for its potential to produce high-quality crystals with preferred orientations and superior photoelectric properties. However, achieving rational epitaxial growth in the fabrication process of perovskite solar cells still remains a challenging task. A thorough understanding of the fundamental principles of epitaxial growth and an appreciation of the unique advantages of the main epitaxial strategies are crucial for the effective application of this technique in the realm of metal halide perovskites. Unfortunately, due to the lack of a comprehensive summary of the epitaxial metal halide perovskite solar cells, current researchers have insufficiently explored the application of epitaxial growth methods, leading to a limited understanding of the underlying principles and immature process development. Therefore, this review systematically summarizes the principle of epitaxial growth technologies, the main epitaxial strategies, and the latest research progresses in its application to perovskite solar cells, aiming to assist readers in better understanding and applying this technique in the context of perovskite solar cells.

“…[ 6–9 ] As an alternative technique, vapor‐based deposition provides a uniform and dense perovskite (PVSK) film, with less influence from solvents and easy integration with commercial thin film photovoltaic manufacturing. [ 10–14 ] Vapor‐based deposition methods commonly include co‐evaporation deposition, [ 10,15,16 ] sequential vapor deposition, [ 17–21 ] and hybrid chemical vapor deposition (HCVD). [ 22–24 ] The co‐evaporation method is carried out by simultaneously sublimating the precursor materials such as PbI 2 and methylammonium iodide (MAI) or formamidinium iodide (FAI) in a high vacuum equipment, which has been demonstrated as an efficient technique to fabricate the highly uniform perovskite films.…”

Hybrid chemical vapor deposition (HCVD) is a promising method for the up‐scalable fabrication of perovskite solar cells/modules (PSCs/PSMs). However, the efficiency of the HCVD‐based perovskite solar cells still lags behind the solution‐processed PSCs/PSMs. In this work, the oxygen loss of the electron transport layer of SnO2 in the HCVD process and its negative impact on solar cell device performance are revealed. As the counter‐measure, potassium sulfamate (H2KNO3S) is introduced as the passivation layer to both mitigate the oxygen loss issue of SnO2 and passivate the uncoordinated Pb2+ in the perovskite film. In parallel, N‐methylpyrrolidone (NMP) is used as the solvent to dissolve PbI2 by forming the intermediate phase of PbI2•NMP, which can greatly lower the energy barrier for perovskite nucleation in the HCVD process. The perovskite seed is employed to further modulate the kinetics of perovskite crystal growth and improve the grain size. The resultant solar cells yield a champion power conversion efficiency (PCE) of 21.98% (0.09 cm2) with a stable output performance of 21.15%, and the PCEs of the mini‐modules are 16.16% (22.4 cm2, stable output performance of 14.72%) and 12.12% (91.8 cm2). Furthermore, the unencapsulated small area device shows an outstanding operational stability with a T80 lifetime exceeding 4000 h.

“…19 Various modification strategies have been proposed to achieve a smooth surface but a high-crystallinity perovskite film, including component engineering, solvent engineering, interface modification, and optimized preparation process. 18,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Nevertheless, challenges remain to achieve high-performance PVSCs. On one hand, a large number of defects are inevitably formed at grain boundaries, resulting in serious nonradiative charge recombination and a short carrier life.…”
