“…To create a high-quality perovskite layer, Moon et al employed MAI and lead acetate (PbAc 2 ) as precursors. By using by-product gas (3MAI + PbAc 2 MAPbI 3 + 2MAAc) to remove the PbAc 2 residue, the crystal development can be accelerated to generate a fully covered, pinhole-free, and highly crystalline perovskite film [52]. Janssen et al used a mixture of PbAc 2 , PbI, and MAI to make a high-quality perovskite layer.…”

Perovskite has emerged as a promising light-harvesting material for solar cells due to its higher absorption coefficient, bandgap tunability, low-exciton binding energy, and long carrier diffusion length. These lead to high power conversion efficiency >25% for thin film-based perovskite solar cells (PSCs). Additionally, PSCs can be fabricated through simple and cost-effective solution processable techniques, which make this technology more advantageous over the current photovoltaic technologies. Several solution-processable methods have been developed for fabrication of PSCs. In this chapter, the advantages and disadvantages of various solution processable techniques and their scope for large-scale commercialization will be discussed.

“…Another technique to improve the crystallinity and overall perovskite film quality is hot‐casting. [ 27,153,184–193 ] In the hot‐casting method, generally a preheated (70–100 °C) perovskite precursor solution is coated on a heated substrate (generally 100–180 °C; sometimes at < 100 °C). As the substrate remains above the crystallization temperature of perovskite during the precursor solution addition, crystallization starts quickly and the remaining solvent promotes the grain growth.…”

technologies based on crystalline silicon, cadmium telluride (CdTe), copper indium gallium selenide (CIGS), etc. [15,16] Tremendous efforts are being given to commercialization of PSCs through improving the device efficiency, stability, and ability to fabricate large-area perovskite films. Though the current efficiency of PSCs is comparable to other matured solar cell technologies, this technology is behind those in terms of stability and large-area fabrication ability. Hopefully, various technologies have come out as potential largearea film fabrication methods, like blade coating, spray coating, slot-die coating, roll printing, etc. [17-20] Furthermore, stability can be improved mostly by encapsulation technologies and using additives in precursor solutions, but still not up to the mark for commercial use, which leaves a huge space for further research. [15,21-24] At the beginning of the perovskite solar cell era, uniform and pinhole-free perovskite film formation was a challenge. It is notable that, pinholes lead to a decrease in shunt resistance and nonuniformity leads to an increase in series resistance, which ultimately produce poor efficiency and stability of the device. Gradually, various technologies had been developed to improve the overall film quality, i.e., to obtain uniform and fully covered films. Among those technologies, the use of antisolvents during the perovskite film formation became very successful to obtain uniform and pinhole-free film, which dramatically increased the efficiency of the devices (also improved the stability to some extent). Antisolvents induce rapid and dense nucleation of perovskite that lead to uniform and pinhole free films. [25] Other effective alternative technologies are additive engineering, [26] hot casting, [27] rapid thermal annealing, [28] and solvent annealing. [29,30] In additive engineering, additives are used generally to slow down the crystallization process of perovskite or defect passivation to improve the crystallinity and optoelectronic properties of the perovskite film. In hot casting, hot precursor solution is coated on a hot substrate for better crystallization that improves the perovskite film quality. In rapid thermal annealing, a high intensity radiation is applied for post-annealing of perovskite film. In solvent annealing, a solvent vapor is allowed to condense on the surface, voids, and grain boundaries of the film, in which the perovskite dissolve and recrystallize to reduce the grain boundaries and pinholes. Interestingly, the best efficiency solar cells are mostly fabricated by using antisolvents. Therefore, a review article on the use of Organic-inorganic metal halide perovskite solar cells are emerging as potential solar energy harvesting tools and can be a tough competitor to already matured solar cell technologies. The success of perovskite solar cells is attributed to superior optoelectronic properties of perovskites, feasible synthesis process, and low fabrication cost. Though perovskite solar cells confront perovskite film quality rela...

“…In addition, the change in the diffraction intensity ratio between (111) and (202) of the hot-casted (iso-BA) 2 (MA) 3 Pb 4 I 13 film implies that the crystal orientation of the film changed substantially [ 18 ]. Moon et al used MAI and lead acetate (PbAc 2 ) as precursors to form a high-quality perovskite layer [ 57 ]. The PbAc 2 residue can be conveniently removed through by-product gas (3MAI + PbAc 2 MAPbI 3 + 2MAAc) to accelerate the crystal growth to form a fully covered, pinhole-free, and highly crystalline perovskite film.…”

Organic–inorganic metal halide perovskite solar cells (PSCs) have recently been considered as one of the most competitive contenders to commercial silicon solar cells in the photovoltaic field. The deposition process of a perovskite film is one of the most critical factors affecting the quality of the film formation and the photovoltaic performance. A hot-casting technique has been widely implemented to deposit high-quality perovskite films with large grain size, uniform thickness, and preferred crystalline orientation. In this review, we first review the classical nucleation and crystal growth theory and discuss those factors affecting the hot-casted perovskite film formation. Meanwhile, the effects of the deposition parameters such as temperature, thermal annealing, precursor chemistry, and atmosphere on the preparation of high-quality perovskite films and high-efficiency PSC devices are comprehensively discussed. The excellent stability of hot-casted perovskite films and integration with scalable deposition technology are conducive to the commercialization of PSCs. Finally, some open questions and future perspectives on the maturity of this technology toward the upscaling deposition of perovskite film for related optoelectronic devices are presented.
