| titleOfInvention | A kind of perovskite film with two-dimensional three-dimensional hierarchical structure and method and application thereof |
| abstract | The invention discloses a perovskite film with a two-dimensional three-dimensional multi-level structure, a method and an application thereof, belonging to the field of solar cells. The preparation method includes depositing a first solution in which an amine ligand is dissolved on the surface of a three-dimensional perovskite, and annealing to complete the pre-embedding of amine molecules on the surface of the three-dimensional perovskite to obtain a preparatory film; and then dissolving a second solution in which an organic ammonium salt is dissolved The solution is deposited on the prepared film, and annealed to obtain a perovskite film with a two-dimensional and three-dimensional hierarchical structure. In the invention, amine ligand molecules are pre-introduced on the upper surface of the three-dimensional perovskite to regulate the growth of the passivation layer of the two-dimensional perovskite to form a two-dimensional passivation layer with controllable dimensions and thickness, thereby obtaining a two-dimensional passivation layer with excellent optoelectronic properties. The three-dimensional hierarchical structure perovskite thin film is used to realize high-performance perovskite solar cells. Based on mixed cation lead halide perovskite, an inversion solar cell device with an energy conversion efficiency of 24.72% is prepared. |
