The invention discloses
indoline-dithienoquinoxaline-dibenzo[a,c]
phenazine dye and application of the dye to a dye-sensitized
solar cell. The dye is a D-A-pi-A pure
organic dye, wherein an
indoline group is taken as an
electron donor; a dithienoquinoxaline group and a
thiophene group are taken as pi bridges; a
cyanoacetic acid group is taken as an
electron donor as well as an anchoring group; meanwhile a dibenzo[a,c]
phenazine group is taken as an electronic assisted donor. The dibenzo[a,c]
phenazine assisted electronic donor is introduced into dye molecules, so that the conjugacy of the dye molecules is enhanced, and the
molecular orbital energy level is regulated; intramolecular
electron transfer is promoted through a rigid plane of conjugated big pi-bridge dioctyl dithienoquinoxaline, andthe accumulation of the dye is restrained through an
alkyl chain, so that the spectrum response range is expanded effectively, and the electronic life is prolonged; the dye has good light absorptioncapability; the dye-sensitized
solar cell based on the dye can obtain big
photocurrent, so that relatively high
photoelectric conversion efficiency is achieved.
