We report on the preparation of MASrBr3 thin films and studied the effects of annealing temperature, annealing time, and precursor solution concentration on crystal growth using XRD and UV-Vis spectroscopy. The composition and crystalline nature of the MASrBr3 thin film were further confirmed using XRD and SEM-EDX. We explored the stability of the MASrBr3 thin films in three solvents and the electrochemical stability of MASrBr3 in an ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. From this study, we observed that MASrBr3 was stable from -1.75 V to 0.35 V vs. Fc/Fc+. Lastly, we determined that the MASrBr3 thin films possess an indirect band gap of 4.52 eV which is corroborated by density functional theory calculations. Taken together, these results indicate that the synthesized MASrBr3 perovskite is viable for future high-bandgap device applications.","abstract_html":"In this thesis, we synthesized and investigated the properties of a Sr-containing hybrid perovskite, methylammonium strontium bromide (MASrBr3).
