We made the ZnO nanorods using wet chemical method. it is so simple, economic and suitable for large-scale production, the quality of the arrayed ZnO nanorods fabricated using these methods are not as good as that of nanorods prepared via VLD, CVDand ED method. We demonstrate that the concentration of precursors have influence on the morphology and optical properties, growth density and its distribution of the arrayed ZnO nanorods can be effectively controlled by using suitable conditions. We tried to study suitable ZnO nanorods growth condition to apply to a organic-inorganic hybrid solar cell, and we made the solar cell and investigated the energy conversion efficiency etc.
