The invention relates to the technical field of photovoltaic cells, in particular to a hole transport material and a preparation method thereof, a solar cell and an optoelectronic device. The hole transport material comprises a hole transport polymer, and the hole transport polymer has at least one of repetitive units shown in formulas (I)-(III). According to the hole transport material provided by the invention, thienopyrrole, carbazole and phenothiazine are adopted as conjugated units of the hole transport polymer, a cyano phosphate group is adopted as an anchoring unit of the hole transport polymer, and through the synergistic effect of the conjugated units and the anchoring unit, the efficiency and stability of a perovskite solar cell are improved, and the service life of the perovskite solar cell is prolonged.

The present invention belongs to the field of perovskites and organic solar cells, and discloses an acridine-based self-assembled hole-selective material having a structure of formula I: #imgabs0#X and Y are each independently selected from hydrogen, alkyl, amino, nitro, alkoxy, and halogen; L is selected from (C2-C18) alkyl, phenyl, naphthyl, anthracenyl, thienyl, benzothienyl, dithienothiophene, dithienothiopyrrole, carbazolyl, and fluorenyl; and A is selected from one of the following groups: #imgabs1# The self-assembled hole-selective material of the present invention has the advantages of high energy level matching, suitable steric hindrance effect, and suitable connecting group length that is conducive to regulating film morphology. It can simultaneously passivate surface defects of a nickel oxide hole transport layer, induce perovskite crystal growth, and reduce energy loss caused by interfacial charge recombination. The self-assembled hole-selective material is applied to an inverted perovskite solar cell device to obtain a solar cell with higher photovoltaic performance and high efficiency and stability.

The application discloses a thienopyrrole fused benzothiadiazole dichroic dye and application thereof.
