Halide perovskite semiconductors can merge the highly efficient operational principles of conventional inorganic semiconductors with the low‑temperature solution processability of emerging organic and hybrid materials, offering a promising route towards cheaply generating electricity as well as light. Following a surge of interest in this class of materials, research on colloidal halide perovskite nanocrystals (NCs) has gathered momentum in the last decade. This talk will highlight several findings of our group on their synthesis, for example our recent study on the influence of various exogenous cations and of acid-based equilibria on the growth of perovskite NCs, and our attempts to control their growth kinetics. The talk will also discuss post-synthesis strategies to improve the stability of the NCs and their subsequent use in light emitting diodes. The last part of the talk will discuss our findings on the ordering of NCs in superstructures, how for example cryogenic temperatures can influence the degree of ordering, and how the degree of order/disorder can be estimated.
