Controlling the growth of halide perovskite films under high relative humidity (RH) ambient conditions is significant for practical applications. Here, we control the antisolvent-assisted growth reactions with a constant temperature and low RH. With the hot casting setup and antisolvent during growth reactions, the synthesis of high coverage and pinhole-free CsPb(Br,I) films is achieved in ambient air.

Article Synopsis
- The study introduces a method to create high-quality nanocrystalline CsPbBr perovskite films using a supersaturated CsBr antisolvent, which helps control crystal growth.
- By limiting the size of the perovskite grains to about 39 nm, the films have significantly improved luminescence compared to the control samples.
- The enhanced properties lead to light-emitting diodes (PeLEDs) that show up to double the current and quantum efficiency, while also reducing leakage current and improving device lifespan.

We demonstrate a compact sample environment for the in situ study of crystallization kinetics of thin films on synchrotron beamlines, featuring atmospheric control, automated deposition, spin-coating, and annealing stages. The setup is suitable for studying thin film growth in real time using grazing-incidence X-ray diffraction techniques. Humidity and oxygen levels are being detected by sensors.

Antisolvent-assisted spin coating has been widely used for fabricating metal halide perovskite films with smooth and compact morphology. However, localized nanoscale inhomogeneities exist in these films owing to rapid crystallization, undermining their overall optoelectronic performance. Here, we show that by relaxing the requirement for film smoothness, outstanding film quality can be obtained simply through a post-annealing grain growth process without passivation agents.

Despite the fast progress of perovskite photovoltaic performances, understanding the crystallization and growth of perovskite films is still lagging. One unanswered fundamental question is whether the perovskite films are grown from top (air side) to bottom (substrate side) or from bottom to top despite 10 years of development. Here, by using grazing incidence x-ray diffraction and morphology characterizations, we unveil that the perovskite films prepared by one-step solution processes, including antisolvent-assisted spin coating and blade coating, follow the downward growth from intermediate phase during thermal annealing.
