| titleOfInvention | Light absorbing layer material of solar cell, ternary cation perovskite solar cell and preparation method thereof |
| abstract | The invention discloses a light absorption layer material of a solar cell, a ternary cation perovskite solar cell and a preparation method thereof; the light absorption layer material is 0%-12% mole percent lead dichlorobromide (MAPbBrCl 2 ) surplus Perovskite material, the original perovskite molecular formula is FA 0.81 MA 0.14 Cs 0.05 PbI 3 . The active layer of the trication perovskite solar cell is prepared by adding methylamine chloride and lead bromide solid to the configured perovskite precursor solution, and then annealing and crystallizing by anti-solvent spin coating method. The invention can effectively improve the nucleation rate of the intermediate phase, can also inhibit the precipitation of lead iodide in the perovskite active layer, can improve the filling factor and open circuit voltage of the device, and further improve the photoelectric conversion efficiency and stability of the perovskite solar cell. sex. The perovskite solar cell prepared by the invention has the advantage of being prepared at low temperature, and is expected to realize large-area preparation of photovoltaic devices. |
