摘要: 采用水热合成技术, 以盐酸、去离子水和钛酸丁酯为反应前驱物, 直接在透明导电玻璃(FTO)衬底上合成了具有金红石结构的TiO2纳米线束阵列。通过改变反应前驱物中钛酸丁酯的添加量, 实现了对TiO2纳米线束阵列密度的调控。以TiO2纳米线束阵列为光阳极、CdS为敏化剂, 组装了量子点敏化太阳能电池器件, 并研究了纳米线束阵列的密度对电池光伏性能的影响。结果表明: 纳米线的密度过高或过低均不利于电池光伏性能的提高。纳米线的优化密度为11.8×106 /mm2, 此时电池的光电转换效率达到了0.947%。

Abstract: Highly oriented single-crystalline rutile TiO2 nanowire bundle arrays on transparent conductive fluorine- doped tin oxide (FTO) substrates were synthesized by hydrothermal method using the precursors of tetrabutyl titanate, deionized water and hydrochloric acid. The density of the TiO2 nanowire bundle can be tuned by changing the concentration of tetrabutyl titanate. Using the nanowire bundle array as the photoanode, CdS as sensitizer, the quantum dot sensitized solar cell (QDSSC) was assembled. The effects of nanowires density on photovoltaic performance of solar cell were investigated. It is found that the cell presents poor photovoltaic performance if the nanowires density is too high or too low. The optimal nanowires density for highest photovoltaic performance is 11.8×106/mm2 when the photoelectric conversion efficiency reaches 0.947%.
