Dye-Sensitized TiO2 Nanotube Solar Cells with Markedly Enhanced Performance via Rational Surface Engineering


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… (More)
