| 中文摘要 | morphology is one of the critical elements in determining the performance of polymer solar cells. as an important member in fullerene family, unsubstituted c-70 is scarcely employed to prepare polymer solar cells as compared with its derivatives, which is ascribed to its poor solution processability from a single organic solvent. hereby, we show a method by using mixed solvent to prepare poly(3-hexylthiophene) (p3ht)/c-70 photoactive layer for high-performance polymer solar cells. composite films spin coated from the solution with different mixed solvents are characterized by optical microscopy, transmission electron microscopy, uv-vis spectroscopy, and photovoltaic (pv) device characterization. as a result, heptane/o-dichlorobenzene (odcb) mixture is found to be a good combination to prepare homogenous p3ht/c-70 film, and a high-performance device is thus obtained. by further optimizing the ratio between the donor p3ht and acceptor c-70 in the composite film, the pv cells with a power conversion efficiency of 2.24% have been achieved, which is much higher than that of the device prepared from odcb-only solution. dynamic light scattering measurement implies that c-70 molecules form aggregates with size of similar to 250 nm in odcb solution, while in heptane/odcb mixture, the aggregates are much smaller, which is responsible for the homogenous p3ht/c-70 film and also high device performance. this paper demonstrates a vivid approach to control the morphology of polymer solar cells, and thus significantly improved performance via deliberately designed solvent system for thin-film deposition. |
