Research Progress on the Fabrication Processes of Metal Halide Perovskite Materials
Metal halide perovskites have become a research hotspot in the field of photovoltaics and optoelec-tronic devices due to their excellent optoelectronic properties,such as high light absorption coefficient,long car-rier diffusion length,and tunable bandgap.The fabrication processes and parameters directly influence material quality and determine the performance and stability of devices.In recent years,researchers have successfully fabricated metal halide perovskite materials with high crystallinity and low defect density by optimizing fabrica-tion methods and conditions,applying them in various optoelectronic devices,such as solar cells,photodetectors,and light-emitting diodes,achieving significant performance improvements.This review summari-zes the research progress in the fabrication of perovskite materials using different methods,compares and analy-zes the characteristics of various fabrication processes,and discusses strategies to optimize film formation by ad-justing process parameters.With the continuous improvement of fabrication techniques and diversification of material systems,the quality of perovskite materials can be further enhanced,bringing the commercialization of perovskite devices closer to realization.
