Since the first report of all-inorganic perovskite solar cells (PSCs) in 2014, more than 200 research articles have been published on this topic, reporting the enhancement in the stabilized power conversion efficiency (PCE) up to 18.4%. All-inorganic PSCs have become one of the most astonishing research domains in the field of perovskite-based photovoltaics. In this Review, significant improvements in all-inorganic PSCs are analytically reviewed, with some insight into the kinetics of intrinsic phase, light, and thermal stability of all-inorganic perovskites. Theoretical calculations specify that there is still a large capacity for further enhancement of device parameters. The critical challenges and the possible elucidations concerning improving the performance of all-inorganic PSCs are also discussed. Our focus is on the assessment of all-inorganic perovskite materials’ properties and the recapitulation of the latest approaches of improving the PCE of corresponding devices in order to introduce new horizons toward commercialization.

全无机钙钛矿太阳能电池：能量学，主要挑战和商业化策略。

自2014年首次发布全无机钙钛矿太阳能电池（PSC）报告以来，已有200多篇关于该主题的研究文章发表，报告称稳定功率转换效率（PCE）增强了18.4％。在基于钙钛矿的光伏领域中，全无机PSC已成为最令人惊讶的研究领域之一。在这篇综述中，我们对全无机PSC的重大改进进行了分析性综述，并对全无机钙钛矿的固有相，光和热稳定性进行了深入研究。理论计算表明，仍有很大的能力可以进一步增强设备参数。还讨论了有关改善全无机PSC性能的关键挑战和可能的阐明方法。
