Abstract

Methylamine-induced thin-film transformation at room-temperature is discovered, where a porous, rough, polycrystalline NH₄PbI₃non-perovskite thin film converts stepwise into a dense, ultrasmooth, textured CH₃NH₃PbI₃perovskite thin film. Owing to the beneficial phase/structural development of the thin film, its photovoltaic properties undergo dramatic enhancement during this NH₄PbI₃-to-CH₃NH₃PbI₃transformation process. The chemical origins of this transformation are studied at various length scales.
