Advances in Synthesis and Defect Properties of Halide Perovskite Nanocrystals: Experimental and Theoretical Perspectives

Abstract

Metal halide perovskites are gaining attention for their interesting optoelectronic properties which result in their promising use for commercial applications. The ease in the fabrication and processability of perovskite nanocrystals with high photoluminescence quantum yield has tremendously attracted the research community and since then various approaches for their synthesis have been developed. This chapter focuses on various size and shape-controlled solution-based synthesis methods for perovskite nanocrystals. Furthermore, synthesis of defect-free perovskite nanocrystals to attain long-term stability along with high efficiency is the primary focus of the growing research community. Therefore, deeper insight into defect properties in perovskite nanocrystals is crucial despite of their defect-tolerant nature. Thus, the purpose of this chapter is twofold (i) to give a complete understanding of various facile synthesis strategies for metal halide perovskite nanocrystals while discussing their advantages and limitations and (ii) to facilitate an in-depth insight about the formation of native defects both from the experimental and theoretical perspectives.
