Solar photovoltaics offers a promising avenue for sustainable power generation, with perovskite solar cells gaining significant interest due to their cost effectiveness and remarkable performance. Lead-based perovskites, while possessing superior electron mobility and carrier properties, raise concerns due to environmental and health risks. Substituting lead with tin holds promise. Tin halide perovskites, particularly with iodine as the halide, exhibit lower band gaps, suggesting heightened efficiency. However, managing the crystallization process, crucial for achieving films with desired morphological properties and crystal phase purity, poses a significant challenge for perovskite materials. Although solvent and additive engineering are extensively explored, their specific effects on the colloidal properties of perovskite suspensions received relatively little attention. This review aims to provide an overview of the world of colloids, shedding light on how the manipulation of colloidal properties in perovskite suspensions can exert a substantial influence on the crystallization kinetics of halide perovskite thin films.

太阳能光伏发电为可持续发电提供了一条有前途的途径，钙钛矿太阳能电池因其成本效益和卓越的性能而引起了人们的广泛关注。铅基钙钛矿虽然具有优异的电子迁移率和载流子特性，但由于环境和健康风险而引起人们的担忧。用锡替代铅是有希望的。卤化锡钙钛矿，特别是以碘作为卤化物，表现出较低的带隙，表明效率更高。然而，结晶过程的管理对于获得具有所需形态特性和晶相纯度的薄膜至关重要，这对钙钛矿材料提出了重大挑战。尽管溶剂和添加剂工程被广泛探索，但它们对钙钛矿悬浮液胶体性质的具体影响相对较少受到关注。本综述旨在概述胶体世界，阐明钙钛矿悬浮液中胶体特性的操纵如何对卤化物钙钛矿薄膜的结晶动力学产生重大影响。
