Abstract

Rutile-phase seagrass-like-arranged TiO2 nanorods have been synthesized by low-temperature template-free hydrothermal method. These TiO2 nanorods have been sensitized by flowers of Sesbania grandiflora, leaves of Camellia sinensis and roots of Rubia tinctorum. The sensitized TiO2 nanorods-based films have been used as photoanode in natural dye-sensitized solar cells. The films were photoelectrochemically active, and the fabricated solar cells had short-circuit photocurrent density (JSC) lying in the range of 3.7–4.7mAcm−2. The efficiency of the fabricated natural dye-sensitized solar cells was found to lie in the range of 0.6–1.036 %, respectively.
