Flexible Lateral Organic Solar Cells with Core-Shell Structured Nanofibers |
| 초록 |
One-dimensional conjugated polymer fibers provide unperturbed percolation pathways for efficient charge transport. This study reports the fabrication of highly photoresponsive one-dimensional (1D) organic semiconductor fibers by using co-axial electrospinning. We produced the core-shell structured 1D organic semiconductor fibers in which the photoactive polymer-fullerene blend are encapsulated with an insulating polymer sheath. It was found that the pristine blend fibers are phase-separated into core and shell phases and contain a uniaxial polymer chain aligned along the fiber direction. These properties are strongly correlated with their highly photoresponsive behavior. The utility of the photoactive fibers in photovoltaic applications was demonstrated by incorporating these fibers into a lateral-architecture photodiode, which was found to exhibit high levels of photocurrent generation. |
