Thiourea functionalized triphenylamine organic dye and application thereof

The invention discloses a thiourea functionalized triphenylamine organic dye and application thereof. The organic dye takes thiourea functionalized triphenylamine as a donor, cyanoacetic acid as a receptor, and thiophene or derivatives thereof as a bridge, double bonds are introduced between the donor and the bridge, the structural formula of the organic dye is as shown in the description, wherein R represents C1-8 alkyl, Ar represents an arbitrary combination of any one or two, R1 and R2 independently represent hydrogen atom or C1-8 alkyl, and n is 1 or 2. The organic dye has wide ultraviolet absorption range, the light current density (Jsc) of the solar cell prepared by the organic dye is high, and the organic dye can be used for preparing solar cells with high photoelectric conversion efficiency.
