Effects of Alkylammonium Choice on Stability and Performance of Quasi-2D Organolead Halide Perovskites

The long-term instability of typical organolead halide perovskites has led to increased interest in Ruddlesden–Popper phase (RPP) perovskites. These materials have been shown to possess high stability under a variety of conditions, including humidity, making them interesting candidates for stable perovskite devices. Here, we report the increased moisture stability of a methylammonium lead triiodide-based (MAPI) RPP perovskite containing...
