Abstract

TiO₂ nanowire arrays were prepared through the low-cost, scalable alkali hydrothermal treatment of Ti threads (Φ = 250 μm) followed by dehydration sintering. Utilization of the nanowire-covered Ti thread as a photoanode allows for the fabrication of flexible, fiber-type dye sensitized solar cells (FDSSC), configurationally different from their traditional flat counterparts. The conversion efficiency of the FDSSC reaches 5.38% through optimizing the length of the nanowires.
