Advances in Metal Halide Perovskite Film Preparation: The Role of Anti-Solvent Treatment

In the past decade, hybrid organic-inorganic perovskite solar cells (PSCs) have attracted significant attention. Since then, the power conversion efficiency has astonishingly reached to 25.5%, situating perovskites at the forefront of all reported solution-processed photovoltaic materials. The research of PSCs has reached a stage where efficiency, stability, and cost need to be simultaneously considered before reaching the threshold for large-scale commercialization. In this article, the recent progress in fabricating high-quality perovskite thin-films adopting anti-solvent strategy is reviewed and the established nucleation and crystal growth mechanisms during the treatment process is discussed. In addition, present challenges and further opportunities of the anti-solvent methodology toward efficient and large-scale PSCs are highlighted. The continuous efforts dedicated to the development of anti-solvent treatment for fabricating high-performance large-area devices may pave the way toward commercial applications of PSCs in the near future.
