Zinc oxide (ZnO) is a wide-band gap IIb-I compound with wurtzite crystal structure, and possesses
semiconducting, pyroelectric, piezoelectric, biosafe and biocompatible properties. With these unique characteristics, ZnO
becomes one of the most important nanomaterials in scientific research and applications nowadays. The diversity of ZnO
nanostructures gives the promising solution to many fields of nanotechnology research, such as dye-sensitized solar cells
(DSSCs). As a low-cost alternative to conventional silicon-based or TiO2-based photovoltaic, one-dimensional (1D) ZnO
nanomaterials exhibit remarkable potentials and meet the clean energy demand. The aim of this review is to present a brief
overview for the preparation methods and properties of 1D ZnO nanotructures and describe their integration into the
DSSCs field. In the end, the perspectives of the 1D ZnO nanostructures applied in DSSCs field are introduced.
