1. Introduction. Perovskite is a yellow, brown, or black minerals, have CaTiO 3 as chemical formula, it obtains its name from mineral named as a calcium titanium oxide and it revealed by Gustav Rose in the Ural Mounts of Russia. The name Perovskite came after Lev Perovski (1792–1856) who was the first discoverer in 1792 (Cheng and Lin, 2010) s …
