采用恒温水浴法在FTO导电玻璃上制备出了ZnO纳米棒阵列,然后对其进行二次生长后得到了ZnO纳米棒阵列/纳米颗粒团聚复合膜,最后它们分别与Pt形成对电极并与电解质溶液组装成染料敏化太阳能电池(DSSC).结果表明:当在模拟太阳光照射(AM 1.5,100 mW/cm2)下时,ZnO纳米棒阵列/纳米颗粒团聚复合膜太阳能电池的短路电流密度Jsc为11.7 mA/cm2,开路电压Voc为0.661 V,填充因子FF为0.384,光电转换效率为3.17%,均明显的高于ZnO纳米棒阵列太阳能电池和ZnO纳米颗粒团聚球太阳能电池.其主要原因是由于ZnO纳米棒阵列/纳米颗粒团聚复合膜染料敏化太阳能电池在具有较高的光生电子传输效率的同时,增加了比表面积和提高了光子的收集效率.
