Performance data of CH₃NH₃PbI₃ inverted planar perovskite solar cells via ammonium halide additives

The data provided in this data set is the study of organic-inorganic hybrid perovskite solar cells fabricated through incorporating the small amounts of ammonium halide NH₄X (X = F, Cl, Br, I) additives into a CH₃NH₃PbI₃ (MAPbI₃) perovskite solution and is published as "High-Performance CH₃NH₃PbI₃ Inverted Planar Perovskite Solar Cells via Ammonium Halide Additives", available in Journal of Industrial and Engineering Chemistry [1]. A compact and uniform perovskite absorber layer with large perovskite crystalline grains, is realized by simply incorporating small amounts of additives into precursor solutions, and utilizing the anti-solvent engineering technique to control the nucleation and growth of perovskite crystal, turning out the enhanced device efficiency (NH₄F: 14.88 ± 0.33%, NH₄Cl: 16.63 ± 0.21%, NH₄Br: 16.64 ± 0.35%, and NH₄I: 17.28 ± 0.15%) compared to that of a reference MAPbI₃ device (Ref.: 12.95 ± 0.48%). In addition, this simple technique of ammonium halide addition to precursor solutions increase the device reproducibility as well as long term stability.
