A sinter-free method to transfer anodized TiO2 nanotube-arrays to a polyethylene terephthalate (PET) sheet is proposed. Since the anodized nanotube-array was crystallized independently before transferring to the PET, the internal charge transport resistance and the charge recombination rate are unchanged for the nanotubes on the PET sheet, and no high temperature sintering process is required. With hydrothermal treatment, the dye sensitized solar cell fabricated utilizing a low temperature bonded nanotube/PET as a photoelectrode exhibits a power conversion efficiency of 5.41%, which is only 0.87% lower than the power conversion efficiency of the solar cell using nanotubes bonded on a conductive glass through high temperature processes.
