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 single-step solvothermal process. Such conveniently used as prepared—without completely removing the residual organics—to obtain suitable screen-printable paste means of use proper polymeric binders. This has successfully implemented fabricate efficient nanorod-based photoelectrodes for dye-sensitized solar cells. They showed an increment overall quantum conversion efficiency comprised between 34% 58% with respect cells based on commercial P25 titanium dioxide nanoparticles. In particular, maximum photocurrent density 16.9 mA/cm2 7.9% obtained, respectively.
