| titleOfInvention | A kind of perovskite solar cell and preparation method thereof |
| abstract | The invention provides a perovskite solar cell and a preparation method thereof. The perovskite solar cell comprises a substrate, a first electrode layer, a first carrier transport layer, a three-dimensional perovskite layer, a passivation layer, a second layer of A carrier transport layer, a second electrode layer, the passivation layer is in contact with the three-dimensional perovskite layer and the second carrier transport layer, the passivation layer includes a uniformly mixed first passivation material and a second passivation material, the first The passivation material is an organic halide salt, and the second passivation material includes at least one of an amino group, a carboxyl group, a phosphono group, and a sulfonic acid group. The passivation layer located between the three-dimensional perovskite layer and the second carrier transport layer can passivate the interface defects, wherein the first passivation material in the passivation layer can passivate the iodine defects, and the second passivation material in the passivation layer can passivate the iodine defects. The passivation material can passivate lead defects, and the first passivation material and the second passivation material cooperate with each other, so that the open circuit voltage, short circuit current density and filling factor of the perovskite solar cell are effectively improved, thereby effectively improving the perovskite solar cell. Photoelectric conversion efficiency of ore solar cells. |
