The invention belongs to the field of perovskite solar cell materials, and discloses a carbazole-based small organic molecule hole transport material. According to the carbazole-based small organic molecule hole transport material, a carbazole intermediate core group fragment is synthesized by utilizing a low-temperature reaction and a bromination reaction; a target product OY1, a target product OY2 and a target product OY3 are obtained by means of synthesis from the carbazole intermediate core group fragment and peripheral triphenylamine micromolecules through an acylation reaction and a coupling reaction; the structures of the target product OY1, the target product OY2 and the target product OY3 are confirmed through a high-resolution mass spectrum characterization means, and the target product OY1, the target product OY2 and the target product OY3 are applied to a perovskite solar cell; the synthesized compound is subjected to photophysic, electrochemical, intrinsic hole mobility and thin film characteristic tests, and in addition, the photovoltaic performance of the perovskite solar cell is represented through tests of output current-voltage, incident monochromatic photon-electron conversion efficiency, long-term stability and the like of the cell device. Due to low cost, easy chemical synthesis and excellent performance, the carbazole-based small organic molecule hole transport material will become a powerful competitor.
