Abstract

Abstract

In order to achieve the implantation of the ZnO nanorod arrays in the nanostructured solar cells, it is necessary to tailor and control the nanorods’ morphology, optical and electrical properties. ZnO nanorods arrays were fabricated by electrodeposition. The physical properties such as the crystalline quality, diameter, density, distance, Al doping concentration, optical band gap energy, near band emission and stokes shift can be adjusted by using Al(NO ₃) ₃and NH ₄NO ₃. The ZnO nanorods’ diameter can be adjusted from 28 nm to 102 nm. The nanorod arrays’ density can be reduced to 2.7×10 ⁹/cm ²by using NH ₄NO ₃, resulting in an increase in the distance between nanorods to 164 nm. The Al/Zn weight ratio was increased to 2.92% by using NH ₄NO ₃, indicating that NH ₄NO ₃can boost Al doping in ZnO nanorods. The ZnO nanorods’ optical band gap energy can be tailored from 3.36 eV to 3.55 eV by using Al(NO ₃) ₃and NH ₄NO ₃and the near band edge emission can also be adjusted. The use of Al(NO ₃) ₃led to the increase of the Stokes shift to 200 meV, but it can be greatly reduced to 26 meV as a result of the NH ₄NO ₃. The use of Al(NO ₃) ₃and NH ₄NO ₃resulted in the fabrication of high-quality ZnO nanorod arrays with effectively tailored morphology and optical properties.
