The perovskite family of solar materials is named for its structural similarity to a mineral called perovskite, which was discovered in 1839 and named after Russian mineralogist L.A. Perovski. The original mineral perovskite, which is calcium titanium oxide (CaTiO 3 ), has a distinctive crystal configuration.
For hybrid perovskites, stability of the perovskite phase is expected within the range 0.813 < τ < 1.107, while the highest tolerance factor limit for hybrid iodide perovskite is between 1.06 and 1.0 [38].
