CsPbI3 nanocrystal films: towards higher stability and efficiency

Perovskite nanocrystals (NCs) have seen unprecedented interest in recent years for their numerous applications in optoelectronic devices. Out of the all-inorganic perovskites, CsPbI3 NCs possess a bandgap closest to the ideal one for solar cells (SCs). CsPbI3 NC-based devices have developed rapidly,...

Description
Summary:Perovskite nanocrystals (NCs) have seen unprecedented interest in recent years for their numerous applications in optoelectronic devices. Out of the all-inorganic perovskites, CsPbI3 NCs possess a bandgap closest to the ideal one for solar cells (SCs). CsPbI3 NC-based devices have developed rapidly, while at the same time they show the most instability of the three halide perovskites. Therefore, there is urgent need to find treatments that improve their stability and enhance their efficiency, thus maximizing their applicability. This review summarizes recent developments of CsPbI3 NC films focusing on the treatments to enhance their stability, as well as on photophysical processes that could help enhance their efficiency in optoelectronic devices.
