In DSSC, the usual way to make good use of the sunlight which works as driving force is to let the light stay longer in the cell through a diffraction layer on the photo-electrode. In previous research, electrospun TiO2 nanofibers added photo electrode achieved 6.22% of energy conversion efficiency, which acted as scattering particles. In this study, in order to enhance the performance of the electrospun TiO2 nanofibers, TiCl4 was treated on the electrospun-nanofiber which had sintered at 850℃ and ground. More densely packed TiO2 nanoparticle in electrospun nonorods provide pathway along which electrons move directly. And the I-V curves showed that 850℃ sintered nanorod mixed TiO2 photo elecrode performed the highest efficiency. |
