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 cell. 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 by 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%.
