  • We find that 2D–3D perovskitoid passivation applied to perovskite solar cells impedes cation migration and decreases carrier recombination at the interface, providing enhanced operating stability at elevated temperatures and increased power conversion efficiencies.

  • Hydriodic acid or hydrogen lead iodide is widely used to stabilize all-inorganic perovskite cesium lead iodide to make high performing solar cells. Here Ke et al. reveal the real composition of the perovskites, where dimethylammonium partially take place of cesium cation at the A-site.
