Chemically Controllable Fabrication of One-Dimensional ZnO Nanostructures and Their Applications in Solar Cells

One-dimensional (1D) ZnO nanostructures have attracted much attention due to their interesting optical and electronic properties, which make them suitable for a wide variety of current and future technological applications, including photodetectors, photovoltaics, photocatalysis, field emissions, gas sensors and solar cells. This review gives a comprehensive overview of recent developments in chemically controllable fabrication of 1D ZnO nanomaterials. We will cover the synthetic techniques including chemical vapor deposition (CVD), metal-organic chemical vapor deposition (MOCVD), hydrothermal technique, solvothermal synthesis, sol-gel method, electrochemical deposition, and nanosphere lithography technique. Finally, we will also highlight their application in the energy conversion system.
