| titleOfInvention | Preparation method of perovskite battery composite material absorption layer |
| abstract | The invention discloses a perovskite battery compositeThe preparation method of the material absorption layer solves the problems that in the prior art, the absorption intensity of sunlight is not high and the absorption spectrum width is narrow by adopting a metal organic halide material as the absorption layer of the perovskite cell. The composite material absorption layer is a thin film which is coated on a substrate and has a core-shell structure; comprises nano gold particles and CH coated outside the nano gold particles 3 NH 3 PbX 3 The material has the molar ratio of gold to lead of 1:5-1:100, and X is halogen. The preparation method comprises the following steps: preparing nano gold solution, adding lead halide and methylamine to obtain nano gold/CH 3 NH 3 PbX 3 And coating the precursor solution of the composite material on a substrate, and drying to obtain the composite material. Au/CH of the invention 3 NH 3 PbX 3 The composite material absorption layer electrode has good uniformity, strong absorbance and high photoelectric conversion efficiency. |
