| titleOfInvention | A kind of perovskite solar cell based on surfactant passivation and preparation method |
| abstract | The invention discloses a perovskite solar cell based on surfactant passivation and a preparation method. By introducing a surfactant passivation layer between a perovskite layer thin film and a hole transport layer of the perovskite solar cell, the To the role of the passivation perovskite layer thin film. The surfactant passivation layer can improve the water contact angle of the surface of the nickel oxide film, and in the subsequent process of preparing the perovskite film, the number of perovskite crystal nuclei can be reduced, so that the crystallinity of the perovskite layer is better, and the crystallinity of the perovskite film is better. The particle size is larger. At the same time, the perovskite solar cell disclosed in the present invention has a higher light absorption coefficient, and because the interface defects of the perovskite are reduced, it has a lower defect state density, and a larger open-circuit voltage, short-circuit current density and Fill factor, and therefore higher photoelectric conversion efficiency, improving overall performance. Moreover, the preparation method of the passivation layer in the perovskite solar cell disclosed in the present invention does not require the participation of any organic solvent, and is more convenient and safe. |
