Perovskite is a mineral composed of calcium titanium oxide (CaTiO2) discovered by a Russian scientist, Gustav Rose, in 1839 and the research was further carried out by Russian mineralogist Lev Perovski therefore this mineral was named as Perovskite.

After that, a lot of research has been conducted and it has been applied to LEDs and solar cells due to its characteristics as a photoelectric device. It has the advantage of fast carrier mobility and low unit price.

However, as there are only advantages, it has disadvantages. When making photoelectric devices, especially LEDs, it has a deep HOMO due to the characteristics of the perovskite material, which makes it difficult to inject holes. And the life is short due to the problem of stability.
