We replaced lead ions with nickel ions in methylammonium lead triiodide (MAPbI3) perovskites and studied their electronic and photophysical properties. We synthesized thin films {using|utilizing|making use of|employing|working with|applying} {solutions|options} containing methylammonium iodide (MAI), PbI2, and NiI2 with varying Pb/Ni precursor ratios. We show that MAPbI3 retains its three-dimensional perovskite structure {in the|within the|inside the} presence of Ni2+. We {were|had been|have been} {able to|in a position to} incorporate {up to|as much as} 30% Ni2+ {before|prior to|just before|ahead of} we note the {appearance|look} of unconverted NiI2 {via|by way of|through|by means of} X-ray diffraction. {Although|Even though|Though|Despite the fact that|While} the structures of NiI2 and PbI2 are isostructural {and the|and also the|as well as the|along with the|plus the} metal ions {have the|possess the} {same|exact same|identical|very same|similar} oxidation states, the bulk material {did not|didn’t} behave as a {solid|strong} {solution|answer|remedy|resolution|option}. {Furthermore|Moreover|In addition|Additionally}, the addition of Ni2+ {thoroughly|completely} quenched the emission of MAPbI3, suggesting that Ni2+ {may|might|could|may possibly|may well|may perhaps} act as a recombination center for excited charge carriers. {Additionally|In addition|Furthermore|Moreover|Also|On top of that}, the {materials|supplies|components} displayed {significant|substantial|considerable|important} instability towards water. {Thus|Therefore|Hence|As a result}, we conclude that {there is|there’s|there is certainly} a {limited|restricted} application for nickel and {perhaps|maybe|possibly|probably} other transition metal ions as a replacement ion for lead in thin-film perovskite photovoltaic devices fabricated in these {conditions|circumstances|situations}. 150529-93-4 Data Sheet Fmoc-Arg(Me,Pbf)-OH Data Sheet PMID:23907521
