TiO2 nanotube arrays were fabricated by anodization of titanium foils in the viscous nonaqueous electrolytes. Effects of anodization parameters on TiO2 nanotube were intensively studied. The photo-electrochemical property of dye sensitized solar cell (DSSC) based on TiO2 nanotube arrays was tested and the influence of TiO2 nanotube morphology on the performance of DSSC was investigated. The result indicates that the growth of TiO2 nanotube arrays with high aspect ratio depends highly on the nonaqueous solution which is enhanced by the applied potential and anodizing time. TiO2 nanotube arrays with aspect ratio up to 313.6 are fabricated in 0.5wt%NH4F in glycerol glycol at 50 V for 17 h. DSSC based on TiO2 nanotube arrays (fabricated in 0.5wt%NH4F in glycerol at 40 V for 13 h) exhibits an open circuit potential of 0.723 V, 2.15 mA/cm2 short circuit current density.
