摘要: Hierarchical TiO2 submicrorods (HTRs) assembled from tiny nanoparticles and nanorods were synthesized through a facile hydrothermal method using titanate glycolate rods as self-template. The as-prepared hierarchical possessed higher surface area (103 m2 g–1) than P25 (NPs) (55 g–1). Composite photoanodes in dye-sensitized solar cells (DSSCs) prepared by integrating the HTRs NPs, photovoltaic conversion efficiency of 8.09% was obtained, which obviously that pristine NPs-based photoanode (5.37%). incorporated hybrid film showed three functions enhancing performance DSSCs: (i) increasing specific for effective adsorption dye molecules, (ii) light harvesting efficiency, (iii) accelerating electron transport films. This work highlights importance tuning structure and...
