Abstract Sodium (Na) doped titanium dioxide (TiO2) nanorods were successfully synthesized by one-step hydrothermal method. The effect of sodium doping in improving the performance of dye sensitized solar cells (DSSC) has been discussed. Field Emission scanning electron micrograph (FESEM) revealed the formation of nanorods and nanoflowers for doped samples. X-ray diffraction (XRD) pattern of doped samples reveal slight shift towards lower angle confirming the effective substitution of Ti4+ by Na+. The photoelectric conversion efficiency of 6% sodium doped TiO2 based DSSC was 1.65% and is 79% higher than the undoped TiO2 based DSSC that exhibited an efficiency of 0.92%. This improvement in efficiency is ascribed due to less electron-hole recombination rate.

用木槿花瓣提取物敏化的基于钠掺杂的 TiO 2 纳米棒的染料敏化太阳能电池的性能增强（洛神花）

摘要 采用一步水热法成功合成了钠(Na)掺杂二氧化钛(TiO2)纳米棒。已经讨论了钠掺杂在改善染料敏化太阳能电池 (DSSC) 性能方面的作用。场发射扫描电子显微照片 (FESEM) 揭示了掺杂样品的纳米棒和纳米花的形成。掺杂样品的 X 射线衍射 (XRD) 图案显示出向较低角度的轻微偏移，证实了 Na+ 对 Ti4+ 的有效取代。6% 钠掺杂 TiO2 基 DSSC 的光电转换效率为 1.65%，比未掺杂 TiO2 基 DSSC 的光电转换效率高 79%，其效率为 0.92%。这种效率的提高归因于较低的电子-空穴复合率。
