Data underlying the publication: Metastable Oxygen-Induced Light-Enhanced Doping in Mixed Sn-Pb Halide Perovskites

Data for SSMC and TRMC results, XRD, UV-Vis-NIR spectroscopy and XPS results in the main manuscript and Supporting Information published with DOI: 10.1021/jacs.4c08924.The raw data were collected in the years 2023-2024, using various structural, compositional, and opto-electronic characterization methods on solution-based spin-coated mixed tin-lead (Sn-Pb) perovskite thin films. All measurements were conducted at room temperature, after varying exposure to oxygen and/or light, or after rest in nitrogen, to study the metastable oxygen-induced light-enhanced doping in the layers. More specifically, all SSMC and TRMC measurements were conducted under nitrogen. The xy data obtained from X-ray diffraction (XRD), UV-Vis-NIR spectroscopy, and X-ray photoelectron spectroscopy (XPS) were imported into Igor Pro (Wavemetrics). In Igor Pro, these xy data are stored as "waves," corresponding to the values on the x and y axes in the plots. Data for Steady State Microwave Conductance (SSMC) and Time-Resolved Microwave Conductivity (TRMC) were collected directly as waves in Igor Pro on the computers connected to the respective microwave-based setups. Igor Pro was used to generate all data plots.For further information on file formats and naming, the units and abbreviations used for all measured values and labels, and instructions for opening or modifying Igor Pro files, please refer to the README.pdf included in the dataset. It is strongly recommended to consult the corresponding publication for guidance on the files in these datasets, as each file name includes a reference to its associated figure. The main manuscript and Supporting Information of the publication contains details about the characterization instruments and additional data processing specifics.
