Properties of moisture tolerant solar cells by encapsulating 3D perovskite with long-chain alkylammonium cation-based 2D perovskites

The data are associated with the open access article "Moisture tolerant solar cells by encapsulating 3D perovskite with long-chain alkylammonium cation-based 2D perovskite" published in "Communications Materials" in 2021. The data are X-ray diffraction patterns, UV-Visible absorption spectra, time-resolved photoluminescence, solar cell performance parameters, electrical parameters, and chemical stability of hybrid organic lead(II) iodide perovskite materials with long alkyl chains (C14-C18). The DOI for the original scientific article is: 10.1038/s43246-021-00200-8.
