Xiao Li Zhang, Yang Chen, Alexander M. Cant, Fuzhi Huang, Yi-Bing Cheng and Rose Amal Crystalline TiO2 Nanorod Aggregates: Template-Free Fabrication and Efficient Light Harvesting in Dye-Sensitized Solar Cell Applications Particle & Particle Systems Characterization 30
Crystalline TiO2 nanorod aggregates with a specific surface area greater than 100 m2 g–1 are prepared through a facile template-free process. When used in photoanode, the aggregates demonstrate a superior charge carrier and greatly enhance the light harvest capacity of the sensitized photoanode. A PCE of excess 9.1% measured using a mask (10.5% lacking a mask) is achieved without device optimization.
