We present in this work a careful study of the different parameters affecting vertically-aligned ZnO-nanorods (NRs) based Dye sensitized solar cells (DSCs). We analyze the effect of synthesis conditions, light intensity, UV light and working temperature, and correlated them to the final photovoltaic properties of the DSC. Although similar studies can be found in the literature for DSCs based on TiO2, this work is, to our knowledge, the first detailed study carried out for DSC based on vertically-aligned ZnO nanorods. The ZnO NRs were grown between 1.6 and 5.2μm long. Electrodes made with 1.6±0.2μm thickness were used to analyze parameters..."
