“…MACl is a special ammonium salt that serves as dopants, crystallization agents, and passivation defect sites and benefits the fabrication of high‐performance PSCs. [ 118 ] Cui and co‐workers compared the effects of FACl and MACl as additives in the crystallization process of α‐FAPbI 3 perovskite. Both FACl and MACl contribute to the evolution of the non‐δ‐FAPbI 3 intermediate phase into α‐FAPbI 3 phase.…”

“…[52][53][54] Therefore, The passivation can be explained as making the perovskite film blunter, [55,56] and it is not only optimizing the structural properties of perovskite films but also improving other aspects such as bandgap, stability, and morphology. [57][58][59][60][61][62] The sensitivity to the external environment is reduced and the external erosion is isolated. After the passivation, the decomposition rate of perovskite is reduced, and the degradation of the device is delayed.…”

Organic-inorganic halide perovskite photovoltaic devices have advanced rapidly in recent years, and the photoelectric conversion efficiency of perovskite solar cells (PSCs) has exceeded 25%. However, the defects from the crystallization process become nonradiation recombination centers and hinder the performance and the stability of PSCs. Defect passivation by tuning grain size and grain boundary (GB) is an effective strategy to reduce the defects on GBs and film surface. Herein, recent progress in the passivation strategy for perovskite films is summarized, including nonstoichiometric passivation, iodide vacancies filling, dimensional engineering, passivation with crosslink, physical passivation, and other passivation methods. These passivation strategies play an important role in improving the quality of perovskite films, adjusting the energy band structure, reducing the density of defect states, and suppressing the nonradiative recombination of carriers. Finally, this review puts forward the development direction of passivation strategies to further improve the performance of PSCs.

All‐inorganic perovskite solar cells (PSCs), such as CsPbX3, have garnered considerable attention recently, as they exhibit superior thermodynamic and optoelectronic stabilities compared to the organic‐inorganic hybrid PSCs. However, the power conversion efficiency (PCE) of CsPbX3 PSCs is generally lower than that of organic‐inorganic hybrid PSCs, as they contain higher defect densities at the interface and within the perovskite light‐absorbing layers, resulting in higher non‐radiative recombination and voltage loss. Consequently, defect regulation has been adopted as an important strategy to improve device performance and stability. This review aims to comprehensively summarize recent progresses on the defect regulation in CsPbX3 PSCs, as well as their cutting‐edge applications in extreme scenarios. We first discuss the underlying fundamental mechanisms leading to the defect formation in the crystal structure of CsPbX3 PSCs, and provide an overview of literature‐adopted defect regulation strategies in the context of interface, internal, and surface engineering. Cutting‐edge applications of CsPbX3 PSCs in extreme environments such as outer space and underwater situations are highlighted. Finally, a summary and outlook are presented on future directions for achieving higher efficiencies and superior stability in CsPbX3 PSCs.This article is protected by copyright. All rights reserved

The performance of hybrid organic–inorganic perovskite solar cells has reached a certified efficiency of 25.5% over the past decade, which has attracted significant attention as a promising candidate for photovoltaic (PV) applications. However, the most efficient perovskite solar cells were produced by the technique of spin coating, which is extremely limited in terms of upscaling production for the commercialization of the technology. Furthermore, the efficiencies of large‐area perovskite modules are still significantly lower than those of lab size solar cells. Thus, there are still some challenges that need to be overcome to bridge the efficiency gap between small‐area perovskite solar cells and large‐area perovskite devices. The first challenge lies in preparing high‐quality perovskite layers by low‐cost and scalable techniques with high reproducibility. Second, selecting and depositing charge extraction layers as well as bottom and top electrodes by scalable and low‐cost techniques are essential tasks. In this review, recent progress and challenges of scalable technologies for solution‐based coating and printing of perovskite PVs are summarized and analyzed. Based on the analysis, strategies and opportunities are proposed to promote the development of stable and efficient large‐area perovskite PV toward commercialization.
