摘要
ZnO/TiO2复合材料综合了TiO2光电转换效率较高和ZnO易于空间定向生长、形貌丰富、能量损耗较少等优点,可有效减少由于电子复合而产生的能量损耗,拓宽光吸收波长,增加光电子的利用率,并进一步提高染料敏化太阳能电池的光伏特性。系统介绍了ZnO/TiO2复合材料的导电原理,综述了近年来国内外关于ZnO/TiO2复合材料应用于染料敏化太阳能电池光阳极的研究进展,并分析了该材料研究的发展方向。
ZnO/TiO2 composite material combines the advantages of TiO2 with high light conversion efficiency and ZnO with rich morphology and less energy consumption.Through this combination,energy loss is effectively reduced due to electron-hole recombination and light absorption wavelength is broadened.In addition,photoelectron utilization is increased and cell photovoltaic characteristics is improved.The conduction principle of ZnO/TiO2 composites is systematically introduced,the recent research progress on the dye-sensitized solar cell based on ZnO/TiO2 composite as anode is also reviewed,and finally the research trend of this material is analyzed.
