| titleOfInvention | High stability perovskite thin film and preparation method thereof |
| abstract | The invention discloses a high-stability perovskite film and a preparation method thereof. The high-stability perovskite film comprises a perovskite light-absorbing layer and a perovskite light-absorbing layer, which is modified by a benzoyl cyanide solution and is coated on the perovskite light-absorbing layer. The hydrophobic interface layer on the surface; the preparation method includes: preparing benzoyl cyanide into a surface modification solution; soaking the perovskite film in the surface modification solution for 30-1800 seconds, and annealing and drying at 70-200° C. The invention performs immersion surface modification on the conventional perovskite film, which can passivate the perovskite light-absorbing layer, improve the quality of the perovskite light-absorbing layer, reduce the defect state density of the perovskite light-absorbing layer, and improve the high stability of the perovskite perovskite layer. The photoelectric conversion efficiency of perovskite solar cells prepared with ore thin films; and benzoyl cyanide, as a surface modification material, can form a hydrophobic interface layer on the outer surface of the perovskite light-absorbing layer, which is beneficial to enhance the performance of high-stability perovskite thin films. hydrophobicity, thereby improving the stability of the prepared perovskite solar cells. |
