Metal halide perovskites
(MHP
s) are considered ideal photovoltaic
materials because of their variable crystalline material composition and excellent optoelectronic properties. However, this compositional variability leads to complex crystallization processes in metal halide perovskite (MHP) film fabrication, resulting in reduced final device performance. Therefore, understanding and controlling the crystallization kinetics of perovskite materials is crucial to improve the stability and performance of perovskite solar cells
(PSCs). In order to study the impact of crystallization characteristics on the properties of MHP films and determine the corresponding modulation strategies, Chen Shanshan 's team from Chongqing University reviewed relevant aspects of MHP crystallization kinetics, systematically summarized theoretical methods, and outlined the modulation technology of MHP crystallization, including solution engineering, Additive engineering and compositional engineering, which help highlight the promise and current challenges of perovskite crystallization kinetics.
