Optimization of Anode Electrode Resistance using Synthesised Graphene Oxide for DSSC Applications

The graphene oxide is synthesized by modified hummer's method. The purification process is done by electrochemical and physical methods. UV Visible, FT-IR, and Raman Spectroscopy characterize the resulting synthesized material. The surface morphology of the wrinkled paper shape is found by SEM and the size of the particles is determined by HR-TEM techniques. The layer distance between the starting material and the final product is calculated by XRD analysis. Through TGA analysis, it is found that the developed material is more stable at higher temperature and subsequently, it tends to be utilized in DSSC applications. The developed GO is coated on a glass plate using the spin coating technique with annealing to convert the normal glass into the conductive glass. And that conductive glass is used as a counter electrode for DSSC. The optimization of electrode resistance is done with the same annealing process by varying the temperature and the number of coatings.
