Abstract

Three-dimensional (3-D) titanium dioxide (TiO ₂) nanoforests with a large surface area and a high electron transport property have been successfully synthesized on transparent conducting oxide (TCO) substrate by using a unique multi-step hydrothermal synthesizing process. First, TiO ₂ nanorods with well-controlled density and length are grown on TCO glass substrate.TiO ₂ nanowires are then synthesized on TiO ₂ nanorods with another hydrothermal process. In comparison with previously reported one-dimensional (1-D) TiO ₂ nanorod arrays, TiO ₂ nanoforests offer a larger surface area for the same height, which is beneficial for achieving higher efficiency dye-sensitized solar cell (DSSC). The experimental results confirm that a conversion efficiency of 3.93% can be achieved with a 5.1 μm long TiO ₂ nanoforest based DSSC under AM1.5 illumination.
