Solution-processed hybrid perovskite semiconductors attract a great deal of attention, but little is known about their formation process. The one-step spin-coating process of perovskites is investigated in situ, revealing that thin-film formation is mediated by solid-state precursor solvates and their nature. The stability of these intermediate phases directly impacts the quality and reproducibility of thermally converted perovskite films and their photovoltaic performance.
溶液处理的混合钙钛矿半导体引起了广泛关注，但对其形成过程知之甚少。本文原位研究了钙钛矿的一步旋涂工艺，揭示了薄膜的形成是由固态前体溶剂合物及其性质介导的。这些中间相的稳定性直接影响热转化钙钛矿薄膜的质量和重现性及其光伏性能。
