| titleOfInvention | All-inorganic perovskite solar cell and preparation method |
| abstract | The invention relates to an all-inorganic perovskite solar cell and a preparation method thereof, wherein the solar cell is prepared from the inorganic perovskiteThe method comprises the steps of 1, adding the CsI into DMSO, adding isopropanol after completely dissolving, filtering precipitates, and drying in vacuum to obtain the processed CsI; step 2, mixing PbI 2 (DMSO)，PbBr 2 (DMSO) and treated CsI, according to CsPbI 2 Dissolving the corresponding element of Br in a molar ratio to prepare a precursor solution; step 3, preparing an electron transport layer on the substrate; spin-coating the solution on the surface of the electron transport layer, and annealing at 30-40 deg.C and 120-200 deg.C for 2-5min respectively to crystallize the film to obtain an inorganic perovskite light absorption layer; and 4, sequentially preparing a hole transport layer and a gold electrode layer on the surface of the absorption layer to obtain the all-inorganic perovskite solar cell. The perovskite battery has the advantages of good water-oxygen stability, good film forming property, simple method and strong repeatability. |
