摘　　要：项目以“新型电池材料”这一研究热点为主题,依托功能材料专业,以案例式教学为切入点,旨在培养探索应用型人才。实验采用水热法在FTO导电基底上制备出纳米棒TiO_(2)薄膜。采用丝网印刷法将P25纳米浆料均匀地涂敷在TiO_(2)纳米棒薄膜上,得到复合TiO_(2)纳米棒/纳米颗粒光阳极。将纳米棒TiO_(2)光阳极和纳米晶TiO_(2)复合光阳极引入到染料敏化太阳能电池(DSSCs)中测试其光电性能。结果表明:TiO_(2)纳米棒/纳米颗粒复合光阳极表现出更优异的光电性能。Taking the research hot topic of“new battery materials”as the theme,relying on the major of functional materials,and taking case-based teaching as the pointcut,aiming at cultivating application-oriented talents,nano-rod TiO_(2)films were prepared on FTO conductive substrate by hydrothermal method.TiO_(2)nanorods/nanoparticle photoanodes were obtained by using P25 nanoparticle paste uniformly coated on TiO_(2)nanorods by screen printing method.Nanorods TiO_(2)photoanodes and nanocrystalline TiO_(2)composite photoanodes were introduced into dye-sensitized solar cells(DSSCs)to test their photoelectric properties.The results showed that TiO_(2)nanorods/nanoparticles composite photoanodes exhibited better photoelectric performance.
