摘要: Abstract Novel TiO2/Nb2O5 core–sheath nanofibers (NFs) were prepared via co-electrospinning. Dye-sensitized solar cells (DSSCs) assembled using NF films as photoanode. The incident photo-to-current conversion efficiency (IPCE), electrochemical impedance spectroscopy (EIS), and photocurrent–voltage (I–V) characteristics measured to evaluate the performance of DSSCs. TiO2/Nb2O5-based DSSCs are superior their TiO2-based counterparts. is enhanced from 4.5 5.8%, which corresponds an increase ca. 30%. And enhancement mechanism was discussed.
