In this work, rare earth (RE) ion RE³⁺ (RE³⁺=Dy³⁺, Ho³⁺ and Er³⁺) doped and undoped In2O3 nanotubes are synthesized by the electrospinning method and the band gap of In2O3 is systemically controlled, depending on the order of doped elements. Dye-sensitized solar cells (DSSCs) based on In2O3:RE³⁺ nanotubes are also fabricated, and significantly improved performance of In2O3–DSSC is observed due to the modulation of the band gap, larger recombination charge transfer resistance and longer electron lifetime.
