摘要
用涂敷法制备了Cdse_xTe_(1-x)薄膜电极0.8>x>0.4,其组成和结构用X射线衍射及X射线荧光光谱进行分析。对薄膜电极的光电化学性能,转换效率,能隙与x的依赖关系进行了研究。通过烧结工艺的改进,获得光电转换效率高于12％的薄膜电极。
CdSexTe1-x thin films were prepared by painting method, in which x is in the range of 0.4-0.8. The films were characterized by X-ray diffraction and X-ray fluorescence spectrum. The dependence of photoelectrochemical behaviours, conversion efficiency and bandgap on x values were studied. Solar energy to electricity conversion efficiency exceeded 12% was obtained by optimizing the annealing process.
