“…Several carbon materials have been used as counter electrode including graphite, carbon nanotubes, activated carbon, graphene and carbon black. A simple example of an application of carbon was demonstrated by Kharkwal et al [146], using an inexpensive pencil lead graphite material as counter electrode. The experiment showed an impressive conversion efficiency of 5.57% and low series resistance, indicating good interface quality with low recombination sites due to the graphite's good charge transport properties.…”

“…Since these carbon based counter electrodes show the excellent electrochemical catalytic activities. [5][6][7][8][9][10][11][12] We have fabricated DSSCs with graphite coated on aluminum as the CE at low cost instead of Pt based CEs. Lithium per chlorate (LiClO 4 ) which is inexpensive and forms highly conductive solutions with carbon based electrodes and perform very well.…”

Hydrothermally synthesized TiO2 nanoparticles were coated onto FTO glass plates and sensitized with Eosin Y (EY) dye. The graphite counter electrode (G) was fabricated by G coating onto the Al and then the cells were assembled by sandwiching the TiO2 photo anode (soaked in EY) and the counter electrode. The assembled FTO/TiO2+EY/Electrolyte/GCE solar cells were subjected to I-V characteristics under a light source of 100mW/cm2. I-V measurement was carried out for Pt CE, and for the G CE based DSSCs. The result cell with Pt CE shows high open circuit voltage (VOC ) 0.717V and fill factor (FF) 0.51, where the G CE based cell gives short circuit current (ISC ) 1.4 mA and photo conversion efficiency (η) 0.56%. Finally, the cell which is fabricated with G counter electrode shows better performance than the Pt CE based cell.
