Abstract

Facile synthesis of TiO₂nanotube branched (length ∼0.5 μm) thin hollow-nanofibers is reported. The hierarchical three dimensional photoanodes (H-TiO₂-NFs) (only ∼1 μm thick) demonstrate their excellent candidature as photoanodes in QD-sensitized solar cells, exhibiting ∼3-fold higher energy conversion efficiency (η = 2.8%, J_sc= 8.8 mA cm⁻²) than that of the directly grown nanotube arrays on a transparent conducting oxide (TCO) substrate (η = 0.9%, J_sc= 2.5 mA cm⁻²).
