“…A high efficiency of 20.56% was achieved after using this modification strategy, which is higher than the pristine PSCs with an average PCE of 17.95%. In a follow‐up work, Gao et al also investigated the formation of hybrid perovskite films by incorporation of CsPbBr 3 NPs . In this work, the authors found that the CsPbBr 3 NPs played a role as nucleation centers, which could slow down the formation speed of the Cs 1− y MA y PbI 3− x Br x absorption layer and passivate the film at the same time.…”

“…Recently, research efforts are focused on the HTL‐free structure (fluorine‐doped tin oxide (FTO)/ETL/CsPbBr 3 /carbon) in CsPbBr 3 PSCs instead of the conventional configuration (FTO/ETL/CsPbBr 3 /HTL/Au) to realize high stability against moisture and thermally induced degradation. Furthermore, CsPbBr 3 can also act as an interlayer to provide a better energy alignment and to passivate detrimental defects in the hybrid PSCs …”

“…In addition to the light harvesting functionality, CsPbBr 3 can also serve as an interface layer in OIH‐PSCs to passivate the interface, lower the energy barrier, and improve carrier injection (Figure ) . For example, Zai et al demonstrated the modification of the FAMAPbIBr‐based hybrid perovskite layer by incorporation of CsPbBr 3 nanocrystals (NCs) .…”

Inorganic perovskite solar cells (PSCs) have attracted enormous attention during the past 5 years. Many advanced strategies and techniques have been developed for fabricating inorganic PSCs with improved efficiency and stability to realize commercial applications. CsPbBr3 is one of the representative materials of inorganic perovskites and has demonstrated excellent stability against thermal and high humidity environmental conditions. The power conversion efficiency of CsPbBr3‐based PSCs has increased significantly from 5.95% in 2015 to 10.91%, and the storage stability under moisture (≈80% relative humidity) and heat (≈80 °C) is more than 2000 h. The outstanding performance of CsPbBr3 PSCs shows great potential in light‐to‐electricity conversion applications. In this review, recent developments of CsPbBr3‐based PSCs including the physico‐chemical as well as optoelectronic properties, processing techniques for fabricating CsPbBr3 films, derivative phase structures, efficiency, and stability of devices are reviewed and discussed. Finally, the challenges and outlook of CsPbBr3 PSCs for future research directions are outlined.

“…Organic‐inorganic hybrid and all‐inorganic metal halide perovskite nanocrystals (NCs) have very recently emerged as interesting materials because of their superior properties for optoelectronic applications. For instance, their unique optical versatility, long charge carrier diffusion length, high photoluminescence quantum yields (PL QYs), tunable bandgaps over the entire visible spectral range, and facile synthesis, all make them increasingly effective in the field of light‐emitting diodes (LEDs), solar cells, and photodetectors …”

In recent years, metal halide perovskite nanocrystals (NCs) have been favored by many researchers due to their unique properties including long carrier diffusion length, high carrier mobility, tunable emission wavelength, and narrow full width at half maximum, making them great application potentials in optoelectronic devices. The photoluminescence quantum yields of perovskite NCs are nearly 100%, and the device efficiency of perovskite NC‐based light‐emitting diodes (LEDs) has been improved significantly from below 0.1% to over 20%. In addition, perovskite NC‐based solar cells and photodetectors have also developed rapidly in recent years. Here, we summarize the synthesis and the basic optoelectronic properties of metal halide perovskite NCs and introduce their applications in LEDs, solar cells, and photodetectors.
