TiO2 nanotube(NT) was firstly prepared on titanium foil by an electrochemical anodization method, and then modified via subsequent deposition of a layer of SrAl2O4:Eu2+ phosphor embedded within TiO2 nanoparticles to fabricate photoanodes of dye–sensitized solar cells(DSSCs). The effect of doping down–conversion Sr Al2O4:Eu2+ phosphor in DSSCs was investigated. SrAl2O4:Eu2+ can effectively convert ultraviolet light to visible light within the range of the dye commonly used in DSSC to increase the photocurrent of DSSC, and enhance the open–circuit voltage by a p–type doping effect. When the ratio of Sr Al2O4:Eu2+ in the doping layer is optimized to be 1wt.%, the photoelectric conversion efficiency of the DSSC reaches 3.09%, which is increased by 38.6%, compared to that of the DSSC without Sr Al2O4:Eu2+ doping.
