Solar cells are becoming a popular, reliable, renewable, and green energy source for the current era due to outstanding characteristics and usefulness over other energy resources. Perovskite solar cell is one of the emerging solar photovoltaics that has provided a new dimension for future renewable energy resources and research. Perovskite was first introduced as solar photovoltaic material in 2009 by a group of Japanese scientists led by Kojima. The group has achieved an efficiency of 3.81% . Since then perovskite solar cells have gotten enormous attention due to several outstanding characteristics including low excitation binding energy , greater absorption coefficient , tunable bandgap , higher carrier mobility , and long carrier diffusion length . Due to continuous research and improvement, the efficiency of perovskite solar cells is increasing continuously and reached more than 26% practically.
