In-situ grazing-incidence X-ray diffraction data of the crystallization process of organic-inorganic methylammonium lead bromide perovskite (MAPbBr3) via employing an isopropanol antisolvent. Raw Data

The dataset contains 400 diffraction images from a 40 second in-situ grazing-incidence wide-angle X-ray scattering measurement of the crystallization process of organic-inorganic methylammonium lead bromide perovskite (MAPbBr3) on a glass substrate. The crystallization is initiated via employing an isopropanol antisolvent during the spin-coating of the perovskite precursor solution. 40 µL of MAPbBr3 solution (4:1 DMF/DMSO solvent mixture) was applied on plasma-cleaned glass substrate in a chamber with kapton windows. The two-phase spin-coating regime included 10 seconds at 1000 rpm followed by 30 seconds at 2000 rpm, 200 µL of antisolvent was dispensed at t = 30 s.

The data was acquired at the P08 Beamline at PETRA III (DESY Hamburg). Acquisition parameters:

• X-ray wavelength: 0.6888 nm

• Sample detector distance: 809 mm

• Incidence angle: 0.5 deg.

• Detector model: XRD 1621 CN3 EHS

• Acquisition rate : 10 frames per second (10 Hz)

• Direct beam position (pixels): 545, 222
