The formation of hybrid organo-metallic perovskites by inverse temperature crystallisation.

Abstract: Hybrid lead perovskites have received much attention over the past decade since they have potential applications in optoelectronic devices and solar cells. Although most devices are grown via thin-film routes, larger crystals can also be produced directly from solutions and demonstrate the rare phenomenon of inverse temperature crystallisation, formation of large perovskite crystals from precursor solutions as temperatures are increased. In this study we will study the changing structure of the solvent as the crystallisation temperature is approached. The two components of the MAPbBr2 perovskite will be mixed together in DMF solvent and heated until crystallisation occurs. Neutron diffraction using isotopic substitution, we will be used to evaluate temperature-dependent changes in solvent structure and role of organic molecules in the formation of these materials.
