| Abstract: | The effect of polyethylenimine (PEI) concentration on the morphology, wire density and size of ZnO nanowire arrays was systematically studied by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscope (SEM). The photovoltaic properties of ZnO nanowire array films were also investigated. It is demonstrated that, for a ZnO nanowire array film obtained from 7.3 mmol·L~(-1) PEI, an energy conversion efficiency of about 0.66% was obtained, which is the highest for ZnO nanowire array films prepared with different PEI concentrations from 3.2 mmol·L~(-1) to 9.3 mmol·L~(-1). |
| Keywords: | nanowire arrays photoanode dye-sensitized solar cells photovoltaic property |
