TL;DR: Crystal defects in highy luminescent colloidal nanocrystals (NCs) of CsPbX3 perovskites are investigated and evidence is provided that the local structure of these NCs always exhibits orthorhombic tilting of PbX6 octahedra within locally ordered subdomains.

TL;DR: Wet ball milling of bulk APbBr3 (A = Cs, FA) mixed with solvents and capping ligands yields green luminescent colloidal NCs with a high overall reaction yield and optoelectronic quality on par with that of NCs of the same composition obtained by hot-injection method.

TL;DR: It is demonstrated that the CdS shell effectively prevents photo-corrosion of PbS, resulting in devices with highly stable photocurrent, and significantly enhanced mean electron lifetime and electron diffusion length provide crucial evidence for the higher efficiency of the cell.

TL;DR: Droplet-based microfluidics can successfully tackle the problem of solving the practical utility and rational synthesis of multinary colloidal NCs in both a time- and cost-efficient manner, and demonstrates the excellent transference of reaction parameters from microfluidity to a conventional flask-based environment, thereby enabling up-scaling and further implementation in optoelectronic devices.

TL;DR: In this paper, the impact of post-synthetic treatments of nanocrystals (NCs) on the performance of Schottky solar cells, where the active PbS nanocrystal layer is sandwiched directly between two electrodes, is investigated.
