文摘

ZnO nanoarray was successfully prepared by a simple chemical bath deposition method on the glass slide deposited with a spin-coated ZnO seed crystal layer. With the measurements of SEM, XRD and UV–vis absorption spectra, the properties of the ZnO nanoarray were characterized in detail. The results show that the ZnO nanoarray is the hexagonal wurtzite structure and grow along the [0 0 1] axis. Furthermore, the energy-conversion property of the device was investigated in such ZnO nanoarray constructed dye-sensitized solar cells (DSCs), which has potential applications in the new-concept photovoltaic devices.
