Influence of Tin Doped TiO<sub>2</sub> Nanorods on Dye Sensitized Solar Cells
The one-step hydrothermal method was used to synthesize Sn-doped TiO<sub>2</sub> (Sn-TiO<sub>2</sub>) thin films, in which the variation in Sn content ranged from 0 to 7-wt % and, further, its influence on the performance of a dye-sensitized solar cell (DSSC) photoanode was s...

| description | The one-step hydrothermal method was used to synthesize Sn-doped TiO<sub>2</sub> (Sn-TiO<sub>2</sub>) thin films, in which the variation in Sn content ranged from 0 to 7-wt % and, further, its influence on the performance of a dye-sensitized solar cell (DSSC) photoanode was studied. The deposited samples were analyzed by X-ray diffraction (XRD) and Raman spectroscopy, which confirmed the existence of the rutile phase of the synthesized samples with crystallite size ranges in between 20.1 to 22.3 nm. In addition, the bare and Sn-TiO<sub>2</sub> thin films showed nanorod morphology. A reduction in the optical band gap from 2.78 to 2.62 eV was observed with increasing Sn content. The X-ray photoelectron spectroscopy (XPS) analysis confirmed Sn<sup>4+</sup> was successfully replaced at the Ti<sup>4+</sup> site. The 3-wt % Sn-TiO<sub>2</sub> based DSSC showed the optimum efficiency of 4.01%, which was superior to 0.87% of bare and other doping concentrations of Sn-TiO<sub>2</sub> based DSSCs. The present work reflects Sn-TiO<sub>2</sub> as an advancing material with excellent capabilities, which can be used in photovoltaic energy conversion devices. |
