What Defines a Halide Perovskite?
The term "perovskite" was first coined by Gustav Rose in 1839 for the CaTiO 3 mineral, who named it after the Russian nobleman and mineralogist Count Lev Alekseyevich von Perovski. Later, in 1926, it was first used as a general term for the crystal structure group by Victor Goldschmidt. 3 In nature, perovskites are primarily found as …
