Modified with gadolinium-containing layer,nanoporous titania electrode and its application in dye-sensitized solar cells were reported.The electrode prepared was characterized with UV-Vis and X-ray diffraction (XRD) techniques.The amount of gadolinium was measured with inductively coupled plasma-optical emission spectrometry (ICP-OES) experiments.The modified electrode showed reduced N3 dye adsorption ability,but increased light conversion efficiency in comparison with the non-modified electrode.The overall conversion efficiencies,determined under 400 W/m2 irradiation with tungsten- halogen lamp at room temperature,were 0.55％ for non-modified and 0.74％ for modified electrodes.
