Traditional antisolvents such as chlorobenzene and trifluorobenzene are highly toxic and volatile, making them unsuitable for large-scale manufacturing. Therefore, green antisolvents are favored in the environmentally friendly preparation of perovskite films.
Jingyu Chen of Southwest Petroleum University and Hua Yu of Dawan University mainly discussed the impact of various green antisolvents on the preparation of perovskite films and analyzed the main chemical characteristics of these green antisolvents. It also explains the impact of green antisolvent treatment on crystal growth and nucleation crystallization mechanisms.
The use of green antisolvents to effectively fabricate large-area devices is introduced, and the mechanism by which green antisolvents enhance stability is analyzed. Subsequently, several green antisolvents capable of preparing highly stable and efficient devices are listed. Finally, we outline the main challenges and future prospects of antisolvent processing, and this review paves the way for industrial manufacturing.
