摘要:本文介绍了一种快捷有效的表面处理技术,可以大大优化有序二氧化钛纳米管阵列染
料敏化太阳能电池。在四氯化钛表面处理后, 微米的二氧化钛纳米管阵列转移至导电玻
璃上封装成的电池在 100 mW/cm2 条件下测试具有高达 % 的转化效率,这是由于
增强的入射光转化效率和光俘获效率。另外,以 5h 制备的纳米管阵列为研究对象,在阳极
氧化结束后升高电压至 100V 并保温不同时间,以这种方法合成的燃料敏华太阳能电池也进
行测试和讨论。

Abstract: In this paper,we report a rapid and inexpensive surface treatment on TiO2 electrodes,
which could be optimized on the highly ordered anodic TiO2 nanotube arrays based dye-sensitized
solar cells. After TiCl4 surface treatments, Dye-sensitized TiO2 nanotube solar cells based on
μm length TiO2 nanotube arrays on FTO glass from the front-side illumination mode subjected to
simulated G irradiation of 100 mW/cm2 exhibited a pronounced power conversion
efficiency (PCE) of %, which is due to the increased incident photon-to-current conversion
efficiency and light-harvesting efficiency. Further more, increasing the voltage to 100 V after
anodization on the 5h TiO2 nanotube arrays and keeping for diff
