摘　　要：基于高度有序的TiO_(2)纳米管阵列,采用连续离子层吸附反应(SILAR)在TiO_(2)纳米管上沉积了CdS量子点,制备了CdS量子点敏化TiO_(2)纳米管太阳能电池。借助X-射线衍射(XRD)、扫描电子显微镜(SEM)等手段对材料的物相、形貌进行了表征。在自然光照射下,使用万用表测试了太阳能电池的短路电流和开路电压,实现了明显的光电转换。本实验原料易得、设备要求简单、知识点多,有利于培养学生查找文献、分析实验数据、科学绘图等综合科学创新能力。Based on highly ordered TiO_(2)nanotube arrays, CdS quantumdots(QDs) were deposited by successive ion layer adsorption reaction(SILAR) process, forming CdS QDs sensitized TiO_(2)nanotube photoanode for application in quantum dots sensitized solar cells. The samples crystal phase, morphology were characterized by XRD, SEM. Under sunlight illumination, the short-circuit current(Isc) and open voltage(Voc) of the solar cell were tested by multimeter, which exhibited obvious photoelectric conversion phenomenon.The materials were easy to obtain, the equipment was simple, and there were many knowledge points. It was conducive to not only cultivate students’ practical ability of searching, reading literature, analyzing experimental data, scientific drawing, but also promote students’ interest in scientific research and comprehensive innovation ability.
