A nanoparticle continuous-coating device based on spatial atomic layer deposition. A first-stage pipeline unit, a second-stage pipeline unit, a third-stage pipeline unit and a fourth-stage pipeline unit which are connected sequentially. The first-stage pipeline unit is used for providing a first precursor and enabling the first precursor to be adsorbed on surfaces of nanoparticles. The third-stage pipeline unit is used for providing a second precursor and enabling the second precursor to react with the first precursor on the surfaces of the nanoparticles, so that a monomolecular thin film layer is generated on the surfaces of the nanoparticles. The second-stage and fourth-stage pipeline units are used for cleaning the nanoparticles and discharging the redundant first precursor, the redundant second precursor or reaction by-products.

Nanoparticle continuous-coating device and method based on spatial atomic layer deposition

The invention discloses a perovskite solar cell and a method of fabrication thereof. The perovskite solar cell sequentially comprises a transparent electrode, a mesoporous P-I-N framework and a counter electrode from the bottom to top; the mesoporous P-I-N framework is composed of an n-type semiconductor layer, an insulating layer, and a p-type semiconductor layer in a sequentially stacked mode, and the n-type semiconductor layer, the insulating layer and the p-type semiconductor layer all comprise mesopores filled with a perovskite material. The preparation method sequentially includes preparing the mesoporous P-I-N framework on a transparent conductive substrate through a spin-coating method or a screen printing method, filling with the perovskite material and preparing the counter electrode layer.
