DSSCs based on directly synthesized and transferred ZnO nanowires. (a) Cross-sectional FESEM image of a ZnO nanowire film during the peeling-off process. (b) FESEM image of the bottom of the ZnO nanowire film after removing from the silicon substrate. (c) J-V plots of DSSCs fabricated using transferred and directly grown ZnO nanowires.
