photovoltaic devices on flexible or rigid substrates. Thiocyanate (SCN)-containing additives,
such as MASCN (MA= methylammonium), have been shown to control perovskite film
crystallization and the film microstructure to achieve effective room-temperature perovskite
absorber processing. Nevertheless, the crystallization pathways and mechanisms of
perovskite formation involved in MASCN additive processing are far from clear. Using in situ …
