Multifunctional Organic-Inorganic Halide Perovskite: Applications in Solar Cells, Light-Emitting Diodes, and Resistive Memory

Perovskite is a well-known structure with the chemical formula ABX₃, where A and B are cations coordinated with 12 and 6 anions, respectively, and X is an anion. When a halogen anion is used, the monovalent A and divalent B cations can be stabilized with respect to a tolerance factor ranging from ~0.8 to 1. Since the first report on ~10% efficiency and long-term stability of solid-state perovskite solar cells (PSCs) in 2012 and two subsequent seed reports on perovskite-sensitized solar cell...
