Emergence of lead halide perovskite colloidal dispersions through aggregation and fragmentation: insights from the nanoscale to the mesoscale

Author affiliations

Abstract

The structural and optoelectronic properties of mixed halide perovskite colloidal precursor dispersions are investigated. With increasing concentration, we observe four stages of growing structures, which affect the thin film morphology: (I) nanoparticles, (II) increasing size of nanoparticles, (III) formation of large aggregates/complex clusters and (IV) fragmentation of large aggregates.
