Abstract

SnO₂ nanofibers and their composites based photoanodes were fabricated and investigated in the application of dye-sensitized solar cells. The photoanode made of SnO₂/TiO₂ composites yielded an over 2-fold improvement in overall conversion efficiency. The microstructure of SnO₂ nanofibers was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). A compact morphology of composites was observed using scanning electron microscopy (SEM). A long charge diffusion length (62.42 μm) in the composites was derived from time constant in transient photovoltage and photocurrent analysis. These experimental results demonstrate that one-dimensional nanostructured SnO₂/TiO₂ composites have a great potential for application in solar cells.
