dc.description.abstract | A new naphthalenediimide (NDI) derivative linked to triphenylamine (TPA) and fullerene (TPA–NDI–C60 triad; S3) was designed, synthesized and characterized. Femtosecond laser transient absorption spectral measurements revealed that fast electron transfer from TPA to the singlet-excited state of NDI occurred to form a charge-separated state (TPA.+–NDI.−–C60) with a rate constant of approximately 1012 s−1, followed by the charge-shift reaction from NDI.− to C60 to produce the charge-separated state (TPA.+–NDI–C60 .−) that decayed by back electron transfer with a rate constant of 4.4×109 s−1 (with a corresponding lifetime of 230 ps). Organic bulk heterojunction solar cells were fabricated using the triad S3 as an n-type semiconductor along with the conventional donor polymer poly(3-hexylthiophene). The power conversion efficiency reached 3.03 % before annealing and 4.85 % after annealing in the optimized devices. To rationalize the performance of these organic photovoltaic devices, atomic force microscopy was used to study the morphology of poly(3-hexylthiophene):S3 blend surfaces, which were found to be well interlaced and free from projections, lumps, or indentations. © 2018 Wiley-VCH Verlag GmbH & Co.
