| titleOfInvention | A Grain Boundary Passivation Method for Perovskite Solar Cells |
| abstract | The invention discloses a grain boundary passivation method for a perovskite solar cell. First, nanometer-sized C 6 H 6 NNaO 6 Pb quantum dots are synthesized by a simple room temperature solution reaction; then a perovskite film is prepared in a one-step method. In the process, the synthesized quantum dots are uniformly dispersed in the anti-solvent, so that the quantum dots are evenly distributed inside the perovskite film, so as to realize the passivation of perovskite grain boundaries. The invention can effectively reduce the defect state density of the perovskite grain boundary and improve the quality of the perovskite thin film, thereby obtaining an efficient and stable perovskite solar cell. The preparation method is simple in process and low in cost, and has a good application prospect in the development of high-performance perovskite solar cells. |
