| titleOfInvention | A wide preparation window and preparation method of spontaneous suede perovskite solar cell |
| abstract | The invention belongs to the technical field of solar cells, and in particular relates to a wide preparation window and a preparation method of a spontaneous suede perovskite solar cell. The electron transport layer is prepared first, and then the perovskite layer, the hole transport layer and the electrode are prepared. The perovskite layer is obtained by coating the perovskite solution, wet film distillation under reduced pressure, and annealing. Among them, the perovskite solution is to dissolve the perovskite precursors (cesium iodide, lead iodide, lead bromide, formamidine iodide, methylamine bromide) into a solvent composed of high volatility and low volatility. obtained in the mixed solvent. During the vacuum distillation process, the highly volatile solvent is removed, and the remaining low-volatile solvent forms a complex with the perovskite precursor to improve the stability of the intermediate film, thus greatly extending the annealing window, and during the annealing process The perovskite surface can spontaneously form a textured surface, and the perovskite film with textured surface can provide light trapping and improve the long-wavelength response of the battery. |
