Abstract

Abstract : This study reports characteristics of dye-sensitized solar cells (DSSCs) with graphene/ZnO nanoparticle bilayer structure. The enhancement of the performance of DSSCs achieved using graphene/ZnO nanoparticle films is attributable to the introduction of an electron-extraction layer and absorption of light in the visible range and especially in the range 300–420 nm. DSSC that was fabricated with graphene/ZnO nanoparticle film composite photoanodes exhibited a V oc of 0.5 V, a J sc of 17.5 mA/cm 2, an FF of 0.456, and a calculated η of 3.98%.
