We report a detailed study on APbX₃ (A=Formamidinium (FA⁺), Cs⁺; X=I^-, Br^-) perovskite quantum dots (PQDs) with combined A- and X-site alloying that exhibit, both, a wide bandgap and high open circuit voltage (V_oc) for the application of a potential top cell in tandem junction photovoltaic (PV) devices. The nanocrystal alloying affords control over the optical bandgap and is readily achieved by solution-phase cation and anion exchange between previously synthesized FAPbI₃ and CsPbBr₃ PQDs. Increasing only the Br^- content of the PQDs widens the bandgap but results in shorter carrier lifetimes and associated Voc losses in devices. These deleterious effects can be mitigated by replacing Cs⁺ with FA⁺, resulting in wide bandgap PQD absorbers with improved charge-carrier mobility and PVs with higher V_oc. Although further device optimization is required, these results demonstrate the potential of FA_1–xCs_x)Pb(I_1–xBr_x)₃ PQDs for wide bandgap perovskite PVs with high V_oc.
