Synthesis of rGO/ZnO Nanorods Composite and its Application as a Photoanode in DSSC Solar Cells

Abstract:

Composite rGO/ZnO NRs (NRs = nanorods) have been a photoanode material in DSSC solar cells. In this study, ZnO NRs were synthesized using a hydrothermal method with the addition of hexamethyl tetraamine (HMTA). The synthesized ZnO NRs was then composited with graphene oxide (GO) synthesized by the modified hummers method. The performance of rGO/ZnO NR composite material with various compositions of ZnO: GO ratio (w/w) as a photoanode has been investigated. The results show that graphene oxide is capable of decreasing the ZnO band gap energy. The composite of rGO/ZnO NRs shows its performance as a photoanode material in DSSCs. The composite with ZnO:GO (w/w) ratio of 1:2 showed better performance than the other rGO/ZnO NRs composite.
