本文提出了一种以层状双氢氧化物（LDH）为前驱体的易烧法制备染料敏化太阳能电池负极材料的新方法。采用尿素法制备了摩尔比Zn:Al = 3:1的ZnAl-LDH。通过在不同温度下煅烧LDH制备混合金属氧化物（MMO），并将相应的氧化物与染料Ruthenizer 535-bisTBA （N719）组装成一系列染料敏化太阳能电池（DSSC）。采用x射线衍射（XRD）、扫描电镜（SEM）、热重和差热分析（TG-DTA）、氮吸收分析和紫外-可见吸收光谱对其基本参数进行了研究。从ZnAl-LDH中得到的MMO带隙（约3.13 eV）与纯ZnO的带隙（约3.2 eV）相似。对太阳能电池的光电行为进行了表征，当煅烧温度为500℃时，太阳能电池的最佳效率为0.0129% (C) 2014 Elsevier B.V.

In this paper, a new simple approach has been developed for the preparation of anode materials for dye-sensitized solar cell by a facile calcination method using the layered double hydroxide (LDH) as a precursor. The ZnAl-LDH with molar ratio Zn:Al = 3:1 is prepared by urea method. The mixed metal oxides (MMO) are prepared by calcining the LDH at different temperatures and a series of dye-sensitized solar cells (DSSC) are assembled by the corresponding oxides and the dye Ruthenizer 535-bisTBA (N719). The basic parameters are investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), thermogravimetric and differential thermal analysis (TG-DTA), nitrogen sorption analysis and UV-Vis absorption spectrum. The band gap of the MMO (about 3.13 eV) obtained from ZnAl-LDH is similar to that of the pure ZnO (about 3.2 eV). The photovoltaic behaviors of solar cells are characterized and the best efficiency is 0.0129% when the calcining temperature is 500 degrees C. (C) 2014 Elsevier B.V. All rights reserved.
