D–π–A organic dyes derived from the indacenodithiophene core moiety for efficient dye-sensitized solar cells

Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed and synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.
