      다국어 초록 (Multilingual Abstract)

      Molecular orientation of conjugated polymers plays a key role inexciton generation/separation and charge transport, and thus significantlyinfluence photovoltaic devices. Herein, we fabricated fiber-basedorganic solar cells and investigated the photovoltaic parameters withdifferent diameters of fibers and PCBM diffusion. The open-circuitvoltage that varies with molecular orientation whether it is face-on oredge-on was observed to differ. The investigation of the open-circuitvoltage dependence reveals that thick fibers have core/shell likestructures with different orientations. Thick fibers have face-on in thecore and edge-on orientations in the shell. The face-on orientations arenot preferentially formed in thin fibers, but the PCBM diffusion caninduce face-on orientations that exist within the intermixed phase. Ourresults may shed a light on better understanding on fiber-based solarcells and suggest a way toward improving photovoltaic efficiency.
