摘要：

We present a novel, facile, and cost-effective method to prepare highly transparent mesoporous films made by anatase TiO2 nanorods that have been synthesized by a single-step solvothermal process. Such nanorods have been conveniently used as prepared-without completely removing the residual organics-to obtain suitable screen-printable paste by means of the use of proper polymeric binders. This method has been successfully implemented to fabricate highly efficient nanorod-based photoelectrodes for dye-sensitized solar cells. They showed an increment of the overall quantum conversion efficiency comprised between 34% and 58% with respect to cells based oil commercial P25 titanium dioxide nanoparticles. In particular, a maximum photocurrent density and solar conversion efficiency of 16.9 mA/cm(2) and 7.9% have been obtained, respectively.
