AbstractIn this study, TiO2nanobelts/nanotubes (TiO2NBs/NTs) photoelectrodes originated from different parameters were in-situ ground of Ti foils through anodization strategy. Subsequently, the resulting samples were investigated through scanning electron microscope (SEM), X-ray diffraction (XRD) and photoluminesence (PL) analysis. SEM and XRD results showed that different fabricating parameters could lead to different TiO2nano-structures with specific morphologies and crystal compositions. Meanwhile, TiO2NBs photoelectrode exhibited the highest separation efficiency of photogenerated charge carriers. Besides, TiO2NBs photoanode also possessed higher photocurrent density and overall power conversion efficiency (PCE) of DSSCs than those of TiO2NTs, in which 11.776 mA·cm-2and 4.91% could be obtained, respectively. The superior PCE value could mainly be attributed to the well anatase crystallinity and high separation efficiency of photogenerated charge carriers, as well as the "belt-like" morphology.
