A spatiotemporal experimental route is reported for the antisolvent vapor diffusion crystal {growth|development} of metal halide perovskites. A computational {analysis|evaluation} combining automated image capture and diffusion modeling enables the determination {of the|from the|in the|on the|with the|of your} {critical|crucial|vital|essential|important} concentrations {required|needed|necessary|essential|expected} for nucleation and crystal {growth|development} from a single experiment. {Five|5} {different|various|distinct|diverse|unique|distinctive} solvent systems and ten distinct organic ammonium iodide salts {were|had been|have been} investigated with lead iodide, from which nine previously unreported compounds {were|had been|have been} {discovered|found}. Automated image capture {of the|from the|in the|on the|with the|of your} mother liquor and antisolvent vials {were|had been|have been} {used|utilized|employed|utilised|applied|made use of} to {determine|figure out|decide|establish|ascertain|identify} {changes|modifications|adjustments|alterations} in {solution|answer|remedy|resolution|option} meniscus positions and detect nucleation {event|occasion} {location|place}. Matching the observations to a numerical {solution|answer|remedy|resolution|option} of Fick’s second law diffusion model enables the calculation of reactant, solvent and antisolvent concentrations at {both|each} the time and position {of the|from the|in the|on the|with the|of your} {first|initial|very first|1st|initially} {stable|steady} nucleation and crystal {growth|development}. A machine {learning|studying|understanding|finding out|mastering} model was {trained|educated} {on the|around the} resulting {data|information} reveals solvent- and amine-specific crystallization tendencies. Solvent systems that interact {more|much more|a lot more|far more|additional|extra} weakly with dissolved lead species {promote|market} crystallization, {while|whilst|although|even though|when|though} {those|these} with stronger interaction can {prevent|stop|avoid|avert|protect against} crystallization {through|via|by means of|by way of} {increased|elevated|improved|enhanced} solubilities. Organic amines that interact {more|much more|a lot more|far more|additional|extra} strongly with inorganic {components|elements} and exhibit {greater|higher} rigidity are {more|much more|a lot more|far more|additional|extra} {likely|most likely|probably} {to be|to become} incorporated into crystalline {products|goods|items|merchandise|solutions}.
