英文摘要	Conference Name:2013 13th IEEE International Conference on Nanotechnology, IEEE-NANO 2013. Conference Address: Beijing, China. Time:August 5, 2013 - August 8, 2013.; IEEE Nanotechnology Council (NTC); China Association for Science and Technology; The Chinese Academy of Sciences (CAS); The Chinese Academy of Engineering (CAE); Chinese Society of Micro-Nano Technology (CSMNT); In this paper, we report the simulation of electrical field distribution and growth of gradient arrayed TiO2 nanotubes by electrochemical anodization. A rectangle electrochemical electrode configuration, in which the end of cathode (Pt wire) is perpendicularly pointed to anode surface (Ti foil), is applied in NH4F glycol electrolyte. Electric field distribution on the surface of the titanium foil shows exponentially decreasing behavior as increasing the distance from the end of cathode. The relationship between nanotube diameter and applied voltage has been analyzed according to the images of Scanning Electron Microscopy (SEM) and simulated electrical distribution. These gradient TiO2 nanotube arrays might be a promising nano-architecture for increasing photon-to-electrical conversion efficiency of dye sensitized solar cells (DSSC). ? 2013 IEEE.
