| titleOfInvention | A kind of method, product and application of preparing surface-modified CeO2 nanomaterial |
| abstract | The invention discloses a method, product and application for preparing surface-modified CeO 2 nanomaterials, and belongs to the field of perovskite solar cells. The method includes: S1 preparing CeO 2 nanoparticles coated with oleic acid; S2 dispersing the CeO 2 nanoparticles coated with oleic acid in a toluene solution; S3 adding an alkaline solvent to the toluene solution of the oleic acid wrapped CeO 2 to decompose Adsorption reaction, centrifugal cleaning after desorption is completed, and milky yellow CeO2 particles are obtained ; S4 uses acetylacetone to modify the milky yellow CeO2 particles ; S5 performs vacuum distillation on the acetylacetone - modified CeO2 solution to obtain Remove excess acetylacetone solvent. The invention also provides a method for preparing perovskite solar cells with different structures by using the CeO 2 nanomaterials modified with acetylacetone. The method of the invention is simple in process, and the prepared modified CeO 2 nanometer material has excellent performance and can be used in perovskite solar cells. |
