Hole transport layer material, preparation method thereof, perovskite solar cell and preparation method of perovskite solar cell

The invention discloses an application of a hole transport layer material in a perovskite solar cell. The hole transport layer material takes spirofluorene as a core and N-aryl naphthylamine as four end groups. The perovskite solar cell comprises a substrate, an electrode, a hole transport layer, an active layer, an electron transport layer and an electrode, wherein the active layer is traditionalmethylamine lead iodide (MAPbI) type perovskite, and the hole transport layer is the N-aryl naphthylamine-based hole transport layer material disclosed by the invention. The perovskite cell preparedby the invention has relatively high open-circuit voltage, relatively high short-circuit current and relatively high filling factor, the highest energy conversion efficiency of the corresponding perovskite cell can reach 17.33%, and in addition, under the condition of no doping, a corresponding perovskite device still has relatively high photoelectric conversion efficiency. The hole transport material can be dissolved in a solvent in a perovskite preparation process and finally remains in a perovskite layer to form a heterojunction structure, so that the hole extraction efficiency is improved,the hole-electron recombination probability is reduced, and the device stability is improved through introduction of N-aryl naphthylamine.
