One of the researching hotspots is the highly-ordered TiO2 nanotube architecture. As a new type of titania nano-material, titania nanotube arrays have drawn extraordinary attention due to its distinctive morphology, notable photoelectrical and hydro-sensitive performance. At 100% sun the new kind of TiO2 nanotube arrays solar cell exhibits an overall conversion efficiency of 5.44%. This paper introduces the preparation methods of titania nanotube arrays, the existing problems and recent progress in titania nanotube arrays solar cell. %K anodic oxidation %K TiO2 nanotube arrays %K dye-sensitized solar cell %U http://link.springer.com/article/10.1007/s11434-007-0254-5
