摘要：

Flighty crystalline SnO2 nanorods with lengths of about 200 nm and diameters of 40-80 nm are synthesized by a hydrothermal method. Because of an efficient electron transport channel along the one-dimensional structure, a dye-sensitized solar cell (DSSC) based on the SnO2 nanorods shows a fast electron transport and a long electron lifetime, resulting in higher power conversion efficiency than the DSSC SnO2-based nanoparticles. To suppress charge recombination at SnO2 nanorods and electrolyte/dye interfaces, we modify SnO2 nanorod electrode with TiO2 compact layer and TiCl4 post-treatment, and the DSSC exhibits a power conversion efficiency of 4.67%.
