Abstract

One-dimensional SnO₂ hollow nanotubes (1D SHNs) were formed via the electron-spinning method. The 1D SHNs exhibit the hierarchical nanostructure and high aspect ratio. The morphological feature allows the solar light sources to be reflected toward the dye molecule absorbed by the TiO₂ layer. The ultraviolet–visible (UV–vis) spectra for diffusion reflectance and transmittance indicate that a thin 1D SHN scattering cluster has a significant impact on the incident light efficiency. Due to these optical characteristics, the dye-sensitized solar cell (DSSC) fabricated with the thin 1D SHN scattering cluster on the conventional TiO₂ photoanode layer exhibits a high solar light-to-energy conversion efficiency of 5.6%. Meanwhile, the DSSC fabricated with the conventional TiO₂ photoanode layer shows a solar light-to-energy conversion efficiency of 4.2%. The enhanced solar light scattering of the SnO₂ nanotube scattering cluster enables an approximate 1.3 fold enhancement in the total solar light-to-energy conversion efficiency.
