【 摘 要 】

Titanium dioxide (TiO2) nanorods have been successfully synthesized through sol- gel method via Anodic Alumina Membrane (AAM) as template. AAM template was removed using 6 M NaOH solution to obtain TiO2nanorods only. Then TiO2nanorods were annealed at 400°C for 2 h. Phase TiO2nanorods were characterized using X-Ray Diffraction (XRD) and morphology of TiO2nanorods were observed using Atomic Force Microscopy (AFM). In addition, the I-V meter was used to determine the DSSC efficiency. The XRD patterns showed that all peaks of synthesized-TiO2indicated anatase phase. AFM images confirmed that TiO2nanorods have diameters in range 18-30 nm. TiO2nanorods were mixed with TiO2nanoparticles having 21 nm in size then it was applied in the DSSC with p-carotene from carrot as dye. The efficiency of DSSC using TiO2mixed-nanorods and nanoparticles increase about 154.20% compare to using TiO2nanoparticles only. It is considered that TiO2nanorod structures can be effective in photon trapping thus many photon interact to dyes to produce many excited-electrons.
