Abstract

The invention discloses a preparation method of a perovskite solar cell based on a nickel oxide hole transport layer. The core innovation of the preparation method is to add an ultraviolet ozone surface treatment technology in the preparation step of a hole transport layer. The problem that the thickness is not uniform and holes can be generated easily for a nickel oxide hole transport layer prepared by spin coating is solved, and the perovskite film in the device is prevented from directly contacting a transparent electrode to affect the performance of the device. Compared with the method ofmodifying a nickel oxide film by doping nanoparticles, a perovskite solar cell prepared by the method of the invention is more stable, and the difference between the devices prepared by the method issmaller.

Description

technical field [0001] The invention relates to the field of preparation of crystalline silicon solar cells, in particular to a preparation method of a perovskite solar cell based on a nickel oxide hole transport layer. Background technique [0002] The development of solar energy technology has roughly gone through three stages: the first generation of solar cells mainly refers to monocrystalline silicon and polycrystalline silicon solar cells, and their photoelectric conversion efficiencies in the laboratory have reached 25% and 20.4% respectively; the second generation of solar cells mainly includes non- Crystalline silicon thin film battery and polycrystalline silicon thin film battery. The third generation of solar cells mainly refers to some new concept cells with high conversion efficiency. Perovskite-type solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials, and belong to the third generation of solar ...
