One-DimensionalTiO2Nanostructures as Photoanodes for Dye-Sensitized Solar Cells

Abstract

Titanium dioxide (TiO2) is star materials due to its remarkable optical and electronic properties, resulting in various applications, especially in the fields of dye-sensitized solar cells (DSSCs). Photoanode is the most important part of the DSSCs, which help to adsorb dye molecules and transport the injected electrons. The size, structure, and morphology of TiO2photoanode have been found to show significant influence on the photovoltaic performance of DSSCs. In this paper, we briefly summarize the synthesis and properties of one-dimensional (1D) TiO2nanomaterials (bare 1D TiO2nanomaterial and 1D hierarchical TiO2) and their photovoltaic performance in DSSCs.
