谢谢指教！ |

Could it be used for dye sensitized solar cell?

发帖数: 65 | 4 I suppose you are talking about growing TiO2 nanotube on ITO substrate. C.
Grimes at PSU did some work on this.The advantage is incident light can
directly reach the active layer in a front-side illumination mode. However,
it is hard to deposit thick Ti on substrate with high quality, which is very
important for the formation of TiO2 NT; also, after anodization and
annealing, the contact between TiO2 NT and substrate might be a problem.
It is also possible to use hydrothermal approach to grow T

hydrothermal process. |

化钛管阵，而此前他们那些看起来很漂亮的管阵都是在毫米级厚度的钛片上得到的。
即使是Grimes，似乎也对用蒸发钛薄层作TNT信心不足，他们组里目前的研究仍然
集中在钛金属片上。

发帖数: 259 | 8 you could spyttering a layer of Aluminum, and anodize it to anodic aluminum
oxide, using ALD to fill the pores, then dissolve the AAO to leave TiO2
nanorods on the Au surface.

发帖数: 100 | 17 我们组一个博士在用C.Grimes 做的TiO2 nanotube on FTO, 1um 长 在1inchx1inch
的FTO 上，电镜图片很漂亮，做出来的device 效率也很高，感觉他们做的TiO2
nanotube array 肯定是能重复且高质量的。至于如何做的就不知道了。 |
