All-inorganic perovskite CsPbX3 nanocrystals (NCs) have made remarkable achievements in optoelectronic applications due to their enhanced stability, low-cost, easy-to-perform synthetic routes, broad emission spectra tunability, and high photoluminescence quantum yields, especially for light emitting diodes (LEDs) and solar cells (SCs). In this perspective, the structure and optoelectronic properties of CsPbX3 NCs are reviewed, and the recent research progresses in LEDs and SCs are presented. Finally, a brief outlook of this field is proposed to point out some important challenges and possible solutions.
