“…However, the band gap of Bi‐based perovskites (>1.8 eV) is still far higher than the ideal band gap of solar cells (1.3–1.4 eV), unless toxic Tl 3+ is doped into Cs 2 AgBiBr 6 . In view of these features of lead‐halide‐based perovskites, Bi‐based perovskites materials with 2 D and ideal 3 D metal–halogen frameworks might be more efficient . It is highly preferable to maintain the 3 D perovskite structure by replacing Pb with low‐toxicity metal cations .…”

“…Except for CsPbI 2 Br (1.92 eV), CsPbIBr 2 with a bandgap of 2.05 eV much larger than 1.73 eV of CsPbI 3 was believed to be very promising for light-harvesting materials, especially for tandem solar cell applications, due to its much better phase stability in comparison with CsPbI 3 . [92] Enormous efforts have been made to optimize the PCE of CsPbIBr 2 -based devices. [93][94][95][96][97] To overcome interfacial nonradiative recombination, ETL/CsPbIBr 2 interface modification was implemented by inserting a SmBr 3 interfacial layer.…”

The large‐scale commercial application of organic–inorganic hybrid perovskite solar cells (PSCs) based on organic hole transport material (HTM) is still hindered by poor long‐term operational stability, although a certified record power conversion efficiency (PCE) as high as 25.2% can be achieved. In the recent several years, all‐inorganic PSCs have received tremendous attention due to their superb thermal and moisture stability and considerable progresses have been witnessed. Herein, the recent advancements of all‐inorganic PSCs are reviewed comprehensively. First, the recent progresses of the strategies for stabilizing the black phase of inorganic perovskites through either increasing tolerance factor or enhancing the energy barrier of phase transition from black to yellow phase are summarized and discussed. Second, the deposition and growth techniques of inorganic perovskite films are discussed. Third, the effective inorganic HTMs in normal all‐inorganic PSCs are described. Fourth, HTM‐free normal all‐inorganic PSCs are discussed. Afterward, the effective inorganic electron transport materials in inverted all‐inorganic PSCs are discussed. Subsequently, the advancements of interface engineering for increasing the PCE and stability of all‐inorganic PSCs are reviewed. Finally, a brief summary and outlook are presented to push up the PCE of all‐inorganic PSCs to over 20% in the near future.

“…Besides the adjacent layers, a move towards an all-inorganic composition also of the perovskite itself is subject of extensive research, since it promises inherently improved stability [35]. Despite being based on the interaction of MA with MAPbI 3 , the MA recrystallization method has already been shown to work on allinorganic perovskite materials as well.…”

Curing perovskites—a way towards control of crystallinity and improved stability

Power conversion efficiencies of lead halide perovskite solar cells have rapidly increased in the decade since their emergence, reaching 25% this year. However, reliable film uniformity and device stability remain hard to achieve and often require precise compliance with complicated protocols, which hampers upscaling towards industrial applications. Here, we explore the potential of an alternative route towards high-quality perovskite films: The reaction between a pre-existing perovskite film and methylamine (MA) gas has been shown to possess the striking ability to both improve film morphology and increase grain size drastically, boosting device performance. This post-deposition treatment could provide the means to decouple film quality from the initial deposition process, thus promising to facilitate upscaling and lowering production costs. Furthermore, such MA gas treatments show great promise regarding the stability of fabricated devices, as they open up the opportunity to reduce or even eliminate the adverse role of grain boundaries in film degradation.
