“…The XRD patterns of ZnO/rGO3 and precursor materials are demonstrated in Figure 6c. The characteristic diffraction peaks of ZnO/rGO3 were observed at 2θ = 31.8, 34.5, 36.3, 47.5, 56.6, 62.8, 67.9, and 69.0°, corresponding to the (110), (002), (101), (102), (110), (103), (112), and (201) crystalline plane of wurtzite structures; similar with the JCPDS File No.36-1451 of ZnO [55,58]. The diffraction peaks of GO and rGO were not observed in the pattern of ZnO/rGO3, because the weight percent of rGO in ZnO/rGO3 composite was low (1%).…”

Graphene-based materials have been widely studied for the fabrication of electrodes in dye-sensitized solar cells (DSSCs). The use of graphene in the cathode is to reduce the amount of platinum (Pt), which in turn is expected to reduce the production cost of DSSCs. Additionally, in the structure of cathode, graphene acts as a supporting material to reduce the particle sizes of Pt and helps to maintain the high efficiency of DSSCs. For anodes, graphene can provide a more effective electron transfer process, resulting in the improvement of efficiency of DSSCs. In this chapter, the use of graphene-based materials for fabrication of cathodes and anodes in DSSCs, including platinum/reduced graphene oxide composite (Pt/rGO) and zinc oxide/reduced graphene oxide composite (ZnO/rGO) is discussed. The fabricated DSSCs were tested using current density-voltage (J-V) curves to evaluate the efficiency. The results of efficiency demonstrate that Pt/rGO is the potential material for fabrication of cathode in DSSCs, which helps to reduce the amount of Pt and maintain the high efficiency. The efficiency values of DSSCs fabricated from ZnO/rGO anodes show that the incorporation of reduced graphene oxide in the ZnO could improve the performance of DSSCs.

“…A maximum PCE of 6.12%, better than Pt CE (5.18%), was achieved when keeping the concentration of nWO3 1% in the TiO2 matrix. Similarly, Siwach et al used MWCNTs for ZnO-graphene based DSSCs, and an efficiency of 2.04%, which is slightly lower than 3.17% of Pt CE based DSSCs, was obtained [165].…”
