This invention discloses a functional modular ordered perovskite thin film, its preparation method, and a solar cell device. The invention constructs a functional modular ordered perovskite thin film by orderly alternating stacking of two-dimensional and three-dimensional perovskite units. Two-dimensional perovskite unit layers are inserted between two three-dimensional perovskite unit layers. Through the ordered functional units, the two-dimensional perovskite units can confine halide ions within the limited space of the three-dimensional perovskite layers. With the increase in the number of two-dimensional perovskite barrier unit layers, the cyclic migration of halide ions inside the three-dimensional perovskite layer under day-night alternation gradually decreases, thereby enhancing the operational stability of the perovskite solar cell and alleviating device fatigue behavior. Through the orderly stacking of two-dimensional / three-dimensional perovskites and the optimization and matching of the unit structure, it is expected to fundamentally solve many stability problems caused by ion migration.
