Abstract

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 TiC_l4 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/cm ² exhibited a pronounced power conversion efficiency (PCE) of 7.37%.
