Metal-free and fluorescent diketopyrrolopyrrole fluorophores for dye-sensitized solar cells

Novel metal-free and fluorescent dipyrrolopyrrole (DPP) dyes consisting of a central bis(lactam)-bearing pendent benzyl or branched hydrocarbon groups as solubilizing fragments and two orthogonal side arms (dimethylaminopropyne and benzoate anion) have been designed and synthesized. The UV/Vis absorption spectra recorded in THF are dominated by intense low-energy π-π absorptions centered at 488 nm or 602 nm, respectively, for the phenyl- or thiophene-based DPP dyes. The fluorescence spectra also display broad bands at 555 nm (τF= 0.57 and ΦF=4.6 ns) for the phenyl- and at 624 nm (ΦF=0.31 and ΦF=3.5 ns) for the thiophene-based molecular structures. Under standard global AM 1.5G irradiation a maximum photon-to-electron conversion efficiency of 2.54% was achieved with dye-sensitized solar cells based on nanocrystalline TiO2 (Jsc=7.5 mAcm-2, Voc=0.49 V, and FF=0.70) for the phenyl-based DPP dye and 1.89% (Jsc=7.1 mAcm-2, Voc= 0.41 V, and FF=0.65) for the thiophene-based DPP dye.
