Organic-inorganic metal-halide-based hybrid perovskite solar cells (SCs) have attracted a great deal of attention from researchers around the globe with their certified power conversion efficiencies (PCEs) having now increased to 25.2%. Nevertheless, organic-inorganic hybrid halide perovskite SCs suffer the serious drawback of instability with respect to moisture and heat. However, all-inorganic perovskite SCs have emerged as promising candidates to tackle the thermal instability problem. Since the introduction of all-inorganic perovskite materials to the field of perovskite photovoltaics in 2014, a plethora of research articles has been published focusing on this research topic. The PCE of all-inorganic PSCs has climbed to a record 18.4% and research is underway to enhance this. In this review, I survey the gradual progress of all-inorganic perovskites, their material design, the fabrication of high-quality perovskite films, energetics, major challenges and schemes opening new horizons toward commercialization. Furthermore, techniques to stabilize cubically phased low-bandgap inorganic perovskites are highlighted, as this is an indispensable requirement for stable and highly efficient SCs. In addition, I explain the various energy loss mechanisms at the interface and in the bulk of perovskite and charge-selective layers, and recap previously published reports on the curtailment of charge-carrier recombination losses.
基于有机-无机金属卤化物的混合钙钛矿太阳能电池（SCs）已引起全球研究人员的广泛关注，其认证的功率转换效率（PCEs）现已提高到25.2%。然而，有机-无机混合卤化物钙钛矿SCs存在严重的缺点，即在湿度和热方面不稳定。然而，全无机钙钛矿SCs已成为解决热稳定性问题的有前途的候选材料。自2014年全无机钙钛矿材料引入钙钛矿光伏领域以来，已经发表了大量聚焦于该研究主题的研究文章。全无机PSC的PCE已攀升至创纪录的18.4%，并且正在进行提高该效率的研究。在这篇综述中，我概述了全无机钙钛矿的逐步进展、它们的材料设计、高质量钙钛矿薄膜的制备、能量学、主要挑战以及朝着商业化开启新视野的方案。此外，强调了稳定立方相低带隙无机钙钛矿的技术，因为这是稳定且高效SCs的不可或缺的要求。此外，我解释了在钙钛矿和电荷选择层的界面及本体中的各种能量损失机制，并回顾了先前发表的关于减少电荷载流子复合损失的报告。
