Lead halide perovskite solar cells (PSCs) with solution processability, low defect concentration, low cost and high output manufacturing have emerged as promising third-generation photovoltaic technologies. After an unprecedented speed of development, the power conversion efficiencies of small-area PSCs have exceeded 25%, and meanwhile large-scale perovskite modules are also on a rapid rise. At this stage, considering the significant progress in the fabrication of perovskite films with controllable morphology and crystallinity, it is necessary to conduct reviews on the updated understandings of the nucleation and crystal growth behaviors of perovskites. This review aims to clarify the related mechanisms of the complex perovskite formation process, and is devoted to giving a timely summary of the recent advances. Strategies for controlling perovskite nucleation and crystal growth are also discussed.

具有解决方案可加工性，低缺陷浓度，低成本和高产量制造的卤化钙钛矿太阳能电池（PSC）已经成为有前途的第三代光伏技术。经过空前的发展速度，小面积PSC的功率转换效率已超过25％，与此同时，大型钙钛矿组件也在迅速提高。在这一阶段，考虑到在具有可控制的形态和结晶度的钙钛矿膜的制造中的重大进展，有必要对钙钛矿的成核和晶体生长行为的最新认识进行回顾。这篇综述旨在阐明复杂钙钛矿形成过程的相关机制，并致力于及时总结最新进展。
