化学浴沉积(CBD)被用于在TiO2单晶纳米棒阵列上形成一CdS量子点薄层,进而组装量子点敏化太阳电池。通过扫描电镜、透射电镜以及其它方法分析发现,结晶良好的CdS量子点均匀包覆于TiO2纳米棒的表面,且组装好的太阳电池显示出良好的光伏特征。优化量子点敏化工艺,获得了高达1.28%的太阳能转换效率。效率不高可能是电子在量子点间的迁移不畅引起的。 Chemical bath deposition (CBD) was used to form a thin layer of CdS quantum dots on a TiO2 single crystal nanorod array, which in turn assembled a quantum dot sensitized solar cell. Scanning electron microscopy, transmission electron microscopy and other methods showed that the well-crystallized CdS quantum dots were uniformly coated on the surface of TiO2 nanorods, and the assembled solar cells showed good photovoltaic characteristics. Optimized quantum dot sensitization process achieved solar conversion efficiencies of up to 1.28%. Inefficient efficiency may be caused by the poor migration of electrons between quantum dots.
