Abstract

To improve the photoelectric performance of dye sensitized solar cells (DSSCs), graphene oxide (GO), upconversion luminescent material NaYbF₄:Ho³⁺ (UC) and porous hollow titanium dioxide microspheres (PHTS) were synthesized to couple with the commercial P25 for improving the light-harvesting of DSSCs. In the composited nanostructure, the GO reduces the internal charge recombination, while the UC doping broadens the absorption spectral range, both of which were applied to the novel PHTS for improving the dye adsorption capacity and light utilization. The P25, P25/GO, P25/UC/GO, P25/UC/GO + PHTS photoanodes were fabricated and the morphology and photoelectric performance were analyzed respectively. Among them, DSSC using P25/UC/GO + PHTS photoanode showed the best performance with the power conversion efficiency (PCE) reaching as high as 9.41%.
