Description

Reduced graphene oxide-phosphorus nanocomposites (RGO-P NC) have been synthesized with a new approach using hydrothermal method as the counter electrode for dye-sensitized solar cell (DSSC). The structure and morphology of as synthesized RGO-P NC were analysed through XRD and SEM. The result show that graphene oxide has reduced to graphene in the hydrothermal reaction process. Simultaneously, by the SEM images it was confirmed that the graphene sheets in composite are exfoliated and decorated with phosphorous. It was studied the current-voltage characteristics of the DSSC as a function of light intensity. It was observed that the efficiency of the RGO-P NC based DSSC depends on the light intensity. The maximum efficiency of 2.77 % was succeed under illumination of 100 mW/cm(2). This result suggests that the RGO-P NC could lead to obtained DSSCs with low cost and high efficiency.
