| Popis: | We report the facile synthesis of blue-colored dyes featuring a diketopyrrolopyrrole (DPP) spacer with dimethylamine and bis(4-dibuotxylphenyl)-phenyl-amine as donor residues (CSD-08 and CSD-09), their spectroscopic, electrochemical and colorific properties, and their application to translucent dye-sensitized solar cells (DSSCs). In the DSSCs fabricated with 5 μm-thick TiO2 photoanodes, CSD-08 and CSD-09 yield power-conversion-efficiencies of 3.43% and 3.62%, respectively, under simulated one sun illumination. |
