The invention discloses preparation and application of an organic hole transport material taking an imidazole derivative as a core, and belongs to the field of perovskite solar power application. Thehole transport material is simple in synthetic route, low in cost, good in solubility, easy to purify and good in stability, and can be used as a hole transport material to be applied to planar perovskite solar cells. A planar perovskite solar cell prepared by the organic hole transport material taking the imidazole derivative as the core designed and synthesized by the invention shows relativelyhigh photoelectric conversion efficiency and good stability. The organic hole transport material taking the imidazole derivative as the core designed and synthesized by the invention provides a new design thought for the hole transport material of the planar perovskite solar cell. 本发明公开了一种以咪唑衍生物为核的有机空穴传输材料的制备及应用，属于钙钛矿太阳能电应用领域。本发明所述的空穴传输材料合成路线简单，成本低廉、溶解度好、易于纯化、稳定性好可作为空穴传输材料应用于平面钙钛矿太阳能电池。采用本发明设计合成的一种以咪唑衍生物为核有机空穴传输材料制备的平面钙钛矿太
