Recently, halide perovskites have become one of the most promising materials for solar cells owing to their outstanding photoelectric performance. Among them, metal halide all-inorganic perovskites (CsPbX3; where X denotes a halogen) show superior thermal and light stability. In particular, the power conversion efficiency (PCE) of perovskite solar cells (pero-SCs) based on a CsPbX3 active layer has shown a steady increase from 2.7% to 19.03% with the improvement of the CsPbX3 crystal quality. In this review, we summarize methodologies that have been employed for controlling the growth of all-inorganic perovskite films so far, including precursor solution deposition, substrate modification, composition doping, and surface engineering. Furthermore, we discuss the effect of the perovskite crystal characteristics on defects and the perovskite film morphology, both of which are closely related to device performance. Finally, conclusions and perspectives are presented along with useful guidelines for developing all-inorganic pero-SCs with high PCE and robust stability.

综述:高性能全无机钙钛矿太阳能电池的晶体生长

近年来,卤化物钙钛矿因其出色的光电性能已成为太阳能电池最有前途的材料之一。其中,金属卤化物全无机钙钛矿(CsPbX 3;其中X表示卤素)显示出优异的热稳定性和光稳定性。特别地,基于CsPbX上钙钛矿太阳能电池(佩罗-SCS)的功率转换效率(PCE)3活性层已显示由2.7%的稳定增加至19.03%与CsPbX的改善3水晶品质。在这篇综述中,我们总结了到目前为止已用于控制全无机钙钛矿薄膜生长的方法,包括前体溶液沉积,基材改性,成分掺杂和表面工程。此外,我们讨论了钙钛矿晶体特性对缺陷和钙钛矿膜形态的影响,这两者均与器件性能密切相关。最后,总结和观点以及开发具有高PCE和稳定稳定性的全无机pero-SC的有用指南。
