Abstract
Page Content
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.
