摘要

Thin films of ZrO_2 were deposited on nanostructured anatase TiO_2 electrodes via sol-gel route and utilised in the assembly of a dye-sensitised solar cells (DSSCs) forming nanostructured core-shell networks.The ZrO_2-coated TiO_2 electrodes were characterised by scanning electron microscopy,X-ray diffraction,X-ray photoelectron spectroscopy and constructing a DSSC.The characterisation concluded that core-shell morphologies were produced with varying ZrO_2 shell thickness without altering the anatase TiO_2 core.When a DSSC was constructed from the ZrO_2:TiO_2 core-shell electrode,the efficiency increased to 2.27% from 0.42% for the uncoated TiO_2 electrode.As the ZrO_2 shell thickness increased,the cell efficiency was reduced.
