Perovskite film and manufacturing method thereof
Provided are a perovskite film and a manufacturing method thereof. The method includes the following steps. A perovskite precursor material is coated in a linear direction on a substrate with a temperature between 100° C. and 200° C., wherein a concentration of the perovskite precursor material is between 0.05 M and 1.5 M. An infrared light irradiation is performed on the perovskite precursor material to cure the perovskite precursor material to form a thin film including a compound represented by formula (1). The perovskite film has a single 2D phase structure or has a structure in which a 3D phase structure is mixed with a single 2D phase structure. (RNH3)2MA(n−1)M1nX(3n+1)  formula (1),
