Enhanced Performance of Dye-Sensitized Solar Cells with GrapheneZnO Nanoparticles Bilayer Structure

Abstract EN

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 Voc of 0.5 V, a Jsc of 17.5 mA/cm2, an FF of 0.456, and a calculated η of 3.98%.
