Abstract
The layered double hydrotalcites (LDH) with molar ratio Zn:Al=2:1 was prepared by urea method. The mixed oxides were prepared by calcining the LDH at different temperatures and a series of dye-sensitized solar cells were assembled by the corresponding oxides and the dye Ruthenizer 535-bisTBA (N719). The basic parameters were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetric and differential thermal analysis (TG-DTA) and UV-Vis absorption spectrum. The photovoltaic behaviors of solar cells were characterized and the best efficiency was 0.015% when the calcining temperature was 500°C.
