Annealing effects on the performance of DSSCs. (a) UV–vis absorption spectra of the N719 dye solutions after nanowire sensitization. The temperature represents the nanowire annealing temperature. (b) J-V curves of the DSSCs fabricated using as-grown nanowires on FTO substrates annealed at different temperatures. The inset shows the dependence of the series resistance on the annealing temperature.(c) XRD data of ZnO nanowires on FTO substrates annealed at different temperatures.
