Hybrid perovskites of the formula A2MX4, A: ammonium substituted organic cation, M: a divalent metal ion and X: a halogen (Cl, Br, I) have attracted considerable attention recently. Their applications include lead-free perovskite solar cell, optoelectronic, exitonic and self-assembly quantum well. The properties of these hybrid perovskites OIHs are functions of A, M and X and there are possibilities to tailor the structure, physical and chemical properties according to the technological application needed. The Co hybrid perovskite is a promising material for lead-free perovskite solar cell applications. Mn organic-inorganic hybrid can be used as catalysis and ultraviolet absorbing materials. Cu hybrid can be used in the application of self-assembly quantum well as well as lead-free perovskite solar cell. The presenter has deposited about 15 of these novel hybrid perovskite materials in Cambridge Crystallographic Data Center (CCDC).
