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.
Lead and other heavy metals in traditional functional perovskites are detrimental for usage in devices, due to the increasing number of applications of low-powered sensors and microenergy electronics.

The base technology for perovskite solar cells is solid-state sensitized solar cells that are based on dye-sensitized Gratzel solar cells. In 1991, O''Regan and Gratzel developed a low-cost photoelectrochemical solar cell based on high surface area nanocrystalline TiO 2 film sensitized with molecular dye [10].Although the PCE of dye …
The ideal cubic perovskite SrTiO 3 has t = 1.00 and ideal ionic radii of r A = 1.44 Å, r B = 0.605 Å and r O = 1.40 Å. If the A-site ion is bigger or the B-site is smaller than the ideal value, the t becomes larger than 1 leading to the face sharing of BO 6 octahedra which is resulting in hexagonal variants of the perovskite structure. These …
