Анотація | An experimental p-n junction device was fabricated by synthesizing ZnO/CuO nanostructures via a hydrothermal process. The structural and optical properties of the ZnO/CuO nanocomposite were studied by X-ray diffraction (XRD), scanning electron microscope (SEM) and photovoltaic measurements. The XRD results showed the formation of the ZnO/CuO nanostructures (hexagonal wurtzite/monoclinic tenorite). The SEM images showed that the ZnO layer consists of vertically oriented nanorods and a CuO layer of nanosheets ranging in size from 1 to 1.5 um.The photovoltaic measurements indicated a certain level of photo-EMF. Vacuum tests revealed peculiar sensitivity to the atmospheric moisture of the ZnO/CuO samples. |
