Crystalline TiO 2 nanorod aggregates with a specific surface area greater than 100 m 2 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.
