The invention relates to a synthetic method of a doping-free hole-transport material based on a fluorenyl ethylene bridged aromatic ring core and an application of the doping-free hole-transport material (FB-OMeTPA and FT-OMeTPA) in a perovskite battery. The method disclosed by the invention is simple in synthesis step and low in cost, and large-scale preparation of the doping-free material can berealized. The doping-free material disclosed by the invention shows good film-forming property and solubility. An ultraviolet-visible absorption spectrum shows that the optical band gap of the doping-free hole-transport material is moderate (2.03eV-2.13eV), and the initial absorption peak is exhibited at about 600 nm. A cyclic voltage-current curve shows that the doping-free hole-transport material obtains a matched highest occupied molecular orbital (HOMO) energy level (about -5.10eV). The doping-free hole-transport material FB-OMeTPA and FT-OMeTPA can acquire photoelectric conversion efficiency of greater than 17% in an organic-inorganic lead-halide perovskite battery, and a huge application prospect is exhibited.
