Abstract

In this study, zinc-reduced graphene oxide (Zn-rGO) and zinc oxide-reduced graphene oxide (ZnO-rGO) composites, synthesized via one-pot chemical deposition at room temperature, was used as mesoporous conducting film in the photoelectrode of dye-sensitized solar cells (DSSCs). The composites were characterized using Raman spectroscopy and scanning electron microscopy. Raman spectroscopy revealed that the grinding process facilitated the synthesis of ZnO in ZGG, which was absent in ZGA. Both ZGA and ZGG were then used as the photoanode in the fabricated DSSCs. Measurements under dark and illuminated conditions reveal a positive and a negative voltage response for ZGG and ZGA, respectively.
