Abstract

We have fabricated transparent ZnO nanorod arrays on the fluorine-doped SnO2 transparent conducting oxide (FTO) glass substrates and used them as the wide band gap semiconductor in dye-sensitized solar cells. Our objectives are to introduce and demonstrate new possibilities in designing the semiconductor morphology. The best performance with this cell structure produced an open circuit voltage (Voc) of 0.64 mV, a short circuit current density (Jsc) of 5.37 mA/cm2, a fill factor (FF) of 0.49, and a conversion efficiency (η) of 1.69 %, primarily limited by the surface area of the nanorod array.
