“…Incidentally noted, a larger water contact angle for FAMACs than MAPbI 3 may be ascribed to the Cs + source in perovskite, which is against moisture. [ 51 ] Overall, the enhanced hydrophobicity, improved film quality, and crystallinity caused by the 4FPAI incorporation are beneficial for improving the stability of perovskite devices.…”

Despite the prominent photovoltaic performance and broad application prospect of perovskite solar cells (PVSCs), a significant challenge for their commercialization is the stability issue. In this study, a fluorinated organic ammonium salt, 4‐trifluoromethyl phenethyl ammonium iodide (4FPAI), is utilized to the spontaneous formation of gradient 2D/3D perovskite which can be prepared by a simple one‐step spin‐coating process with low‐dimensional phases on the surface and high‐dimensional phases at the bottom. The introduction of 4FPAI leads to an improved charge transport as well as reduced non‐radiative recombination. The optimal 4FPAI‐based PVSC exhibits a power conversion efficiency (PCE) of 22.12% which is higher than that of the control PVSC without the 4FPAI treatment (20.87%). Meanwhile, the encapsulated 4FPAI‐based device remains about 88% of its initial PCE under an ambient air exposure for 80 days, demonstrating its improved moisture resistance compared to the reference device. This work provides an important strategy for fabricating high‐efficiency and long‐term stable 2D/3D PVSCsThis article is protected by copyright. All rights reserved.

“…Table 1 shows the performance statistics of MA-based wide bandgap perovskite solar cells. MAPbX perovskites have a stable photovoltaic phase in the operational window of photovoltaic devices [ 17 ]. In 2014, Huang et al fabricated perovskite film MAPbI 3−x Br x with a band gap of 1.72 eV via the two-step preparation method, in which an isopropanol solution with mixed MABr and MAI was spin-coated onto the PbI 2 layer, followed by a solvent annealing process [ 18 ].…”

Perovskite/silicon tandem solar cells have garnered considerable interest due to their potential to surpass the Shockley–Queisser limit of single-junction Si solar cells. The rapidly advanced efficiencies of perovskite/silicon tandem solar cells benefit from the significant improvements in perovskite technology. Beginning with the evolution of wide bandgap perovskite cells towards two-terminal (2T) perovskite/silicon tandem solar cells, this work concentrates on component engineering, additives, and interface modification of wide bandgap perovskite cells. Furthermore, the advancements in 2T perovskite/silicon tandem solar cells are presented, and the influence of the central interconnect layer and the Si cell on the progression of the tandem solar cells is emphasized. Finally, we discuss the challenges and obstacles associated with 2T perovskite/silicon tandem solar cells, conducting a thorough analysis and providing a prospect for their future.

“…[137,138] Wide bandgap (w-Eg) perovskites (Eg ≥ 1.60 eV) are another interesting group of perovskite materials, because of the high efficiency potential in w-Eg perovskite tandem solar cells in combination with silicon. Despite the peculiar crystallization of these compounds often resulting in porous films, [139] Benard et al recently reported slot-die coated layers of a w-Eg perovskite with a composition of MA x FA 1-x Pb(I,Br) 3 . [91] The MACl addition was also found here to play an important role in the formation of high-quality films, which could achieve a cell efficiency stabilized at 17.5%.…”

Solution‐coating processes are promising methods to form active layers with low‐cost input in the industrial development of perovskite solar devices. Among available coating processes, of particular interest are those capable of producing uniform coatings with small defect distribution over large areas at high speeds, referred to as scalable methods. Slot‐die coating is one of these methods. It involves the meniscus coating of liquids or solutions over a static or moving substrate. This review discusses recent advances in slot‐die coating of active layers used in perovskite solar cells (PSCs) and modules (PSMs). Various strategies to control ink spreading over substrates, wet film drying, and post‐coating crystallization of light‐absorbing perovskite layer are outlined along with different approaches and materials used in post‐deposition defects healing. Then, commonly used solvents for perovskite ink formulation are analyzed based on their specific rheology and potential effect on human health and equipment safety. Also, precursor materials, solvents, and strategies to obtain desirable properties and morphology in the slot‐die coating of charge‐transporting layers are discussed. Lastly, an analysis of the performance of slot‐die coated perovskite solar mini‐modules and future perspectives on this topic conclude this review.
