Perovskite CsPbBr3 crystals: growth and applications

Abstract

The CsPbBr₃ perovskite material has excellent optoelectronic properties such as large light absorption coefficient, high carrier mobility, long diffusion length, etc., and thus it shows good application prospects in solar cells, photodetectors, high-energy radiation detectors and other fields. Compared with polycrystalline thin films, a single crystal perovskite without grain boundaries has better photoelectric performance, showing photovoltaic potential with higher efficiency and stability. Therefore, the fabrication of CsPbBr₃ perovskite single crystals is very important to further explore the potential of single crystal perovskites in various applications. This review systematically summarizes the latest research progress of perovskite CsPbBr₃ crystal growth in recent years, and introduces its applications in photodetectors, high-energy radiation detectors, and solar cells. Finally, the challenges and perspectives of perovskite CsPbBr₃ crystals are discussed.
