Experimental evaluations of the F-DSSC performances. (a) Measured current density versus voltage curves for the all-solid F-DSSC (as a function of the TNT length). The straight lines are adapted from references [22]. (b-d) Comparisons of the current density versus voltage curves between semi- and all-solid F-DSSCs of different TNT lengths in the anodized and annealed Ti wires. Terminology: 1-semi-solid means the semi-solid F-DSSC fabricated from the TNTs which average length (or TNT layer thickness) is 1 μm, 35-all-solid means the all-solid F-DSSC fabricated from the TNTs which average length (or TNT layer thickness) is 35 μm, and so on. Average TNT length or TNT layer thickness: (b) 1 μm; (c) 11.5 μm; and (d) 35 μm. (e) Experimentally measured current density versus voltage curves for the semi-solid F-DSSCs as a function of the TNT length.
