Abstract

Zinc Oxide (ZnO) is one of the important Transparent Conducting Oxides (TCO) for thin film photovoltaic cells with respect to performance and cost reduction. When used in photovoltaic cells, the surface roughness of ZnO is required in order to increase the amount of light going inside the cells (Light Trapping). In this paper we present the surface morphology in connection with the fiber texture of ZnO films at different experimental conditions. The structural properties of the ZnO films grown by the method of radio frequency sputtering and Chemical Vapour Deposition (CVD) with the special effort to make surface roughness (Surface Texturing) are presented. The influence of the control over the fiber texture, surface mobility of the adatoms and the dissociation of water vapour during growth are explained.
