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.

高效稳定的全无机钙钛矿太阳能电池

尽管经认证的记录功率转换效率(PCE)高达90%,但长期运行稳定性差仍然阻碍了基于有机空穴传输材料(HTM)的有机-无机杂化钙钛矿太阳能电池(PSC)的大规模商业应用。可以达到25.2%。近年来,由于其优异的热稳定性和湿稳定性,全无机PSC受到了极大的关注,并取得了长足的进步。在此,全面回顾了所有无机PSC的最新进展。首先,总结并讨论了通过增加耐受因子或增强从黑相转变为黄相的能垒来稳定无机钙钛矿黑相的策略的最新进展。第二,讨论了无机钙钛矿薄膜的沉积和生长技术。第三,描述了正常全无机PSC中有效的无机HTM。第四,讨论了无HTM的正常全无机PSC。之后,讨论了倒置全无机PSC中有效的无机电子传输材料。随后,回顾了用于提高全无机PSC的PCE和稳定性的界面工程技术的进步。最后,提出了简短的总结和展望,以期在不久的将来将所有无机PSC的PCE提升到20%以上。讨论了反相全无机PSC中有效的无机电子传输材料。随后,回顾了用于提高全无机PSC的PCE和稳定性的界面工程技术的进步。最后,提出了简短的总结和展望,以期在不久的将来将所有无机PSC的PCE提升到20%以上。讨论了反向全无机PSC中有效的无机电子传输材料。随后,回顾了用于提高全无机PSC的PCE和稳定性的界面工程技术的进步。最后,提出了简短的总结和展望,以期在不久的将来将所有无机PSC的PCE提升到20%以上。
