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%.
