Abstract

In this paper we demonstrate a branched Rutile TiO₂ nanorod structure which used as a model architecture for efficient photoelectrochemical devices for simultaneously offers a large contact area with the electrolyte, excellent lighttrapping characteristics, and a highly conductive pathway for charge carrier collection. We developed a facile hydrothermal synthesis method to achieve rutile TiO₂ nanorod arrays on FTO substrate without use of any acid. The morphology of nanorods can be finely tuned by changing the growth parameters, and the potential of the as-made rutile TiO₂ nanorods in perovskite solar cells was evaluated, showing power conversion efficiency up to 11.1%.
