a In situ GIWAXS patterns in the range of q = −0.1–1.1 Å−1 for a film of MAPbI3 treated with a solution of 5 mg/mL VBABr in IPA. i-PbI2 = intercalated PbI2. b Contour map of azimuthally integrated GIWAXS patterns for MAPbI3. c Contour map and d in situ GIWAXS patterns for a film of (MAPbBr3)0.05(FAPbI3)0.95 treated with a solution of 1 mM VBABr in 3:97 IPA:CF. Patterns were collected with an incident angle of 0.1˚.
