In recent years, ZnO, a wide band gap semiconductor, has been investigated extensively due to its high surface-to-volume ratio. Intrinsic properties and potential values for application in many fields, such as gas sensors, catalyst , LED ,solar cells and so on. In the present work, we studied the effect of optical properties of Mg-doped ZnO nanorods by one step hydrothermal method for solid perovskite-sensitized solar cells. In this method, Zn(NO3)2.6H2O was used as a precursor and Mg(NO3)2.6H2O was the dopant. Different concentration of Mg-doped ZnO nanorods synthesis by hydrothermal method. Many properties of the ZnO thus can be modulated by doping of Mg. Mg doping can increase the band gap and dismiss the absorption coefficient, which is critical to the application in invisible light region. ZnO has been doped with Mg to enlarge the band gap. |
