以ZnO纳米棒为模板，采用液相反应沉积法在ITO衬底上制备了高度取向的TiO 2纳米管。通过改变ZnO纳米棒模板的直径和长度，可以有效地控制TiO 2纳米管的直径和长度，以适合用于混合太阳能电池。P3 HT/PCBM的混合物渗透到TiO 2纳米管之间的间隙，形成杂化太阳能电池。使用高度取向的TiO 2纳米管的混合太阳能电池的开路电压、短路电流密度、填充因子和功率转换效率分别为646 mV、9.95 mA cm-2、51.6%和3.32%，远高于在其他相同条件下测试的基于ZnO纳米棒的混合太阳能电池的1.2%，并且显著高于0.7%。与文献中报道的相同类型的混合太阳能电池相比。纳米TiO 2管的高度取向、直径小、比表面积大有利于提高其能量转换效率。
Highly oriented TiO2 nanotubes have been fabricated using ZnO nanorod template through liquid reactive deposition on the ITO substrates. The diameter and length of TiO2 nanotubes can be effectively controlled for the suitable use for a hybrid solar cell by varying the diameter and length of the ZnO nanorod template. A mixture of P3HT/PCBM was infiltrated into the gaps between TiO2 nanotubes to form hybrid solar cells. The open circuit voltage, short circuit current density, fill factor, and power conversion efficiency of the hybrid solar cell using highly oriented TiO2 nanotubes were 646 mV, 9.95 mA cm−2, 51.6%, and 3.32%, respectively, much higher than 1.2% of hybrid solar cell based on ZnO nanorods tested under otherwise identical conditions and significantly higher than 0.7% of the same type hybrid solar cells reported in literature. The enhancement of the power conversion efficiency could be resulted from the highly oriented TiO2 nanotubes with smaller diameter and large specific surface area for the ...
