通过电化学阳极氧化制备的高度有序的阳极 TiO2 纳米管阵列用钌染料 N-719 敏化，产生染料敏化 TiO2 纳米管太阳能电池。光阳极TiO2纳米管的合理表面处理显着提高了器件性能。通过 TiCl4 处理，结合优化条件下的氧等离子体暴露，使用 14 μm 厚的 TiO2 纳米管阵列在背面照明模式下生产的染料敏化 TiO2 纳米管太阳能电池，在 100 mW/cm2 的模拟 AM 1.5 G 辐照下，表现出高达 7.37% 的功率转换效率 (PCE)。
Highly ordered anodic TiO2 nanotube arrays fabricated by electrochemical anodization were sensitized with ruthenium dye N-719 to yield dye-sensitized TiO2 nanotube solar cells. Rational surface treatments on photoanode TiO2 nanotubes markedly improved the device performance. With TiCl4 treatment, in conjunction with oxygen plasma exposure under optimized conditions, dye-sensitized TiO2 nanotube solar cells produced using 14-μm-thick TiO2 nanotube arrays in backside illumination mode subjected to simulated AM 1.5 G irradiation of 100 mW/cm2 exhibited a pronounced power conversion efficiency (PCE) of 7.37%.
