| titleOfInvention | A preparation method of perovskite thin film based on magnetic field control |
| abstract | The invention discloses a method for preparing a perovskite thin film based on magnetic field control, and belongs to the technical field of solar cells. The main steps include: using a mixed solution of lead iodide (lead(II) iodide, PbI 2 ) and methylamine iodide (CH 3 NH 3 I ) through a film-forming process that is easy to realize industrialization, and introducing a certain frequency during the preparation process And strength of the rotating magnetic field, and then heat treatment, you can get a dense smooth, uniform perovskite crystal film. The method of the present invention can also prepare smooth and dense perovskite films without using vacuum equipment, glove boxes, etc., and has the advantages of low cost and large-area preparation. The perovskite crystal thin film obtained by this method is used as a light-absorbing material in thin-film solar cells, and the prepared cell device has high efficiency and good stability, which is very important for realizing low-cost preparation and industrialization of high-efficiency perovskite solar cells of great value. |
