“…Wang et al utilized a one-step anti-solvent deposition method utilizing diisopropyl ether as a dripping solvent to produce highly uniform and crystalline CH 3 NH 3 PbI 3 perovskite films. PSCs produced through the antisolvent deposition method with diisopropyl ether solvent had an average PCE of 17.67% and a highest PCE of 19.07% [171] compared to perovskite films fabricated using toluene, chlorobenzene, or chloroform. Therefore, diisopropyl ether is the most appropriate solvent for the antisolvent deposition method.…”

The recent rapid development in perovskite solar cells (PSCs) has led to significant research interest due to their notable photovoltaic performance, currently exceeding 25% power conversion efficiency for small-area PSCs. The materials used to fabricate PSCs dominate the current photovoltaic market, especially with the rapid increase in efficiency and performance. The present work reviews recent developments in PSCs’ preparation and fabrication methods, the associated advantages and disadvantages, and methods for improving the efficiency of large-area perovskite films for commercial application. The work is structured in three parts. First is a brief overview of large-area PSCs, followed by a discussion of the preparation methods and methods to improve PSC efficiency, quality, and stability. Envisioned future perspectives on the synthesis and commercialization of large-area PSCs are discussed last. Most of the growth in commercial PSC applications is likely to be in building integrated photovoltaics and electric vehicle battery charging solutions. This review concludes that blade coating, slot-die coating, and ink-jet printing carry the highest potential for the scalable manufacture of large-area PSCs with moderate-to-high PCEs. More research and development are key to improving PSC stability and, in the long-term, closing the chasm in lifespan between PSCs and conventional photovoltaic cells.

“…Benefiting from the advances of various film deposition techniques, such as one-step spin coating [13,21], two-step sequential solution deposition [22,23] and inkjet printing fabrication [24,25], unprecedented progress in the improvement of the efficiency of PSCs has been made. To obtain high-quality perovskite films based on these techniques, researchers control the perovskite morphology by optimizing the solvents for processing [26], varying the annealing temperature [27], adjusting the processing additives [28], sophisticated engineering of the solvent [12,14] and annealing of the solvent [29,30].…”

“…Deng et al [13] produced efficient PSCs with diisopropyl ether as the antisolvent, which perfectly overcome this barrier. As shown in Figure 2, perovskite films fabricated by an antisolvent deposition process, where large perovskite crystals pack densely without pinholes, exhibit a smoother and more uniform morphology compared to those prepared by the traditional onestep method without antisolvent treatment.…”

“…For example, it has been widely recognized that the PCE of the PSCs depends largely on the morphology and the crystalline quality of the perovskite layer [12]. Therefore, recent major challenges are to simultaneously control the film morphology and the crystalline quality and to prepare high-quality perovskite films with complete surface coverage, uniform morphology and large well-crystallized grains [13][14][15][16]. At the same time, research also focuses on the preparation of large-area perovskite films of high quality to obtain large-area perovskite solar modules [17,18].…”

Perovskite solar cells (PSCs) are set to be game changing components in next-generation photovoltaic technology due to their high efficiency and low cost. In this article, recent progress in the development of perovskite layers, which are the basis of PSCs, is reviewed. Achievements in the fabrication of high-quality perovskite films by various methods and techniques are introduced. The reported works demonstrate that the power conversion efficiency of the perovskite layers depends largely on their morphology and the crystalline quality. Furthermore, recent achievements concerning the scalability of perovskite films are presented. These developments aim at manufacturing large-scale perovskite solar modules at high speed. Moreover, it is shown that the development of low-dimensional perovskites plays an important role in improving the long-term ambient stability of PSCs. Finally, these latest advancements can enhance the competitiveness of PSCs in photovoltaics, paving the way for their commercialization. In the closing section of this review, some future critical challenges are outlined, and the prospect of commercialization of PSCs is presented.

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...
