“…The high frequency and a smaller peak phase from bode plot represents the low charge transfer resistance and the low frequency and higher peak phase of the device represents the high charge‐transfer resistance. The maximum phase obtained for RGO/NMP based device is 3.8° and frequency of 5159.2 Hz (Table ) . The phase value obtained for RGO/nafion based device is 18.4° and frequency of 677.8 Hz was obtained (Table ).…”

In dye sensitized solar cells (DSSC), the counter electrode (CE) plays a significant role in electro catalytic reaction in redox region to achieve maximum power conversion efficiency (PCE) of the DSSC. The graphene oxide (GO) is synthesized by Hummer's method and converted to reduced graphene oxide (RGO) by thermal method. The effect of binders such as NMP, PVP, and nafion for RGO are investigated. The field emission scanning electron microscope (FESEM) of RGO shows the fine layers like structure. The surface area of the RGO is found to be 110.16 m2 g−1 by Brunauer–Emmett–Teller (BET) method and pore volume 0.5182 cm3 g−1 of RGO by Barrett–Joyner–Halenda (BJH) method. The Raman spectra is used to analyze the structural defects and changes of GO and RGO. The crystallite size of GO is 18.6 nm, and RGO is 20.9 nm calculated from the Raman spectrum. For analyzing the electro catalytic properties of the RGO/NMP/PVP, RGO/NMP, and RGO/nafion based CE materials cyclic voltammetry is performed and its maximum current density was measured. The composition of RGO/NMP/PVP based CE exhibits better electro‐catalytic properties when compared to other RGO/NMP and RGO/nafion based counter electrodes. Maximum PCE exhibited by RGO/NMP/PVP CE based DSSC is 5.8%.

In the present study, we report a simple method to synthesize silver (Ag)-polypyrrole (PPy)/graphene (Gr) nanocomposite as efficient electrode materials for supercapacitor application. The probable interaction between Ag nanoparticles with both PPy and Gr were characterized by FTIR, UV-visible, and Raman spectroscopies. The morphological analysis confirmed that the Gr sheets are uniformly coated by PPy and in the coated Gr sheets there is the presence of Ag nanoparticles. The Ag-PPy/Gr nanocomposite achieved the highest specific capacitance of 472 F/g at a 0.5 A/g current density. Better energy and power density also obtained for the nanocomposite. The presence of both Ag nanoparticles and Gr is the main reason for the enhancement of the electrochemical properties of the nanocomposite. Based on the superior electrochemical properties, the nanocomposite can be used for nextgeneration supercapacitor electrode material.
