Preparation of TiO2 nanotube arrays through two-step anodization for efficient dye sensitized solar cells
(0) INTRODUCTION Dye-sensitized solar cells (DSSCs) represent one of the most promising of cost-effective concepts for light-to-electricity conversion. The configuration of a liquid-junction DSSC consists of a wide band gap semiconductor photoanode, dye sensitizer, redox electrolyte, and platinized-FTO counter electrode. Commonly, TiO2 nanoparticle network film is used as the photoanode. In contrast to TiO2 nanoparticle network film, 1D TiO2 nanostructures can effectively improve charge transport properties due to the absence of an extended random walk network and grain boundary effects. Among various 1D TiO2 nanostructures, anodic TiO2 nanotube arrays are suggested to be superior in photoelectrochemical performance due to their 1D architecture, which provides vectorial electron transfer pathway and then reduced recombination 1-3.
