| titleOfInvention | A method for preparing perovskite thin film based on solution method, perovskite thin film and application |
| abstract | The invention belongs to the field of thin film solar cells, and discloses a preparation method of a perovskite thin film based on a liquid phase method. The method is specifically as follows: depositing a perovskite precursor solution on a substrate to form a liquid film, then placing a thermal conduction module on a hot stage, and suspending the substrate on the hot stage for baking, when the perovskite thin film is formed. After the color on the substrate gradually deepened, the substrate was removed and placed on the surface of the hot stage for annealing to obtain a perovskite thin film. In the present invention, a heat conduction module is placed on the heat stage at the center of the substrate, thereby enhancing the baking temperature of the substrate in the center region, so that the perovskite crystal nuclei on the edge region and the center region of the substrate are simultaneously precipitated, The problem of film non-uniformity due to hysteresis in nucleation is improved. At the same time, the method can adjust the size and shape of the heat conduction module, so as to ensure that the central area of the substrate will not cause the hysteresis of crystal nucleus precipitation due to the increase of the size of the substrate. |
