| titleOfInvention | All-inorganic perovskite solar cell with high open-circuit voltage and preparation method thereof |
| abstract | An all-inorganic perovskite solar cell with high open-circuit voltage is prepared by the following steps: s1: preparing an electron transport layer on a clean conductive substrate; s2: preparing a perovskite light absorption layer on the electron transport layer prepared in step S1; s3: spin-coating a trifluoroethyl methacrylate solution on the perovskite light absorption layer prepared in the step S2, and performing heat treatment to obtain a trifluoroethyl methacrylate film serving as an interface passivation layer; s4: and (4) coating a carbon electrode layer on the interface passivation layer prepared in the step S3 by a blade coating method to serve as a back electrode layer, and performing heat treatment to obtain the all-inorganic perovskite solar cell with high open-circuit voltage. According to the invention, trifluoroethyl methacrylate is used as an interface passivation material of the perovskite light absorption layer for the first time, and the interface passivation of the perovskite light absorption layer is realized by utilizing the coordination of fluorine ions and carbonyl functional groups and lead ions in the perovskite light absorption layer, so that the open-circuit voltage and the photoelectric conversion performance of the battery are improved. |
