| 英文摘要 | Three diketopyrrolopyrrole (DPP) dyes (ICD-3, ICD-4 and ICD-5) with a D--pi-A conjugation were designed and synthesized, where a symmetric phenyl-DPP-phenyl unit was used to connect a substituted diphenylamine and a thienyl acrylic acid, and two n-hexyl or 2-ethyl-hexyl chains were introduced on the periphery of the DPP macrocycle. The dyes were characterized by photophysical, electrochemical, and density functional theory calculations. Among the three dyes, the ICD-5-based DSC afforded the best photovoltaic performance: a short circuit photocurrent density (J(sc)) of 16.34 mA/cm(2), an open circuit voltage (V-oc) of 753 mV, and a fill factor (FF) of 0.74, corresponding to an overall conversion efficiency (eta) of 9.10% using I /I-3 redox couple-based liquid electrolyte under AM 1.5 conditions. The experimental results demonstrate that the DPP-based sensitizer is a promising option for DSCs, and rational molecular engineering is crucial for constructing highly efficient charge transfer sensitizers.
