| titleOfInvention | A kind of perovskite solar cell based on 3,4,9,10-perylenetetracarboxylic dianhydride modification and preparation method |
| abstract | The invention discloses a preparation method of a perovskite solar cell modified based on 3, 4, 9, 10-perylene tetracarboxylic dianhydride, which comprises preparing a mesoporous electron transport layer on transparent conductive glass; Soak in 3, 4, 9, 10-perylene tetracarboxylic dianhydride solution, rinse and dry to obtain a composite electron transport layer; drop the perovskite precursor solution on the composite electron transport layer by anti-solvent titration at high speed spin coating, In the spin coating process, the anti-solvent solution containing 3, 4, 9, 10-perylene tetracarboxylic dianhydride was titrated, and the perovskite light-absorbing layer was obtained by heating and annealing; the hole-transporting layer precursor solution was spin-coated on the perovskite light-absorbing layer to obtain A hole transport layer; a perovskite solar cell is obtained by vapor-depositing a gold electrode on the hole transport layer. The method is simple in process and easy to operate. The surface of the prepared perovskite solar cell has large, uniform and complete crystal grains, and can passivate the perovskite at the same time. The defect state of the charge extraction interface inside and on both sides of the mine significantly improves its charge extraction efficiency and enhances its resistance to moisture and light. |
