N2 - In this study, we proposed and investigated the performance of DSSCs with the multi-walled carbon nanotube (MWCNT) on the counter electrode(CE). The 0.45cm 2 DSSC device of glass/FTO/TiO 2 blocking layer/TiO 2(8.5um)/Dye(N719)/ electrolyte (C6DMII,GSCN)/MWCNT/FTO/ glass was fabricated, and then the surface morphology of CEs and the energy conversion efficiency of the DSSC device were characterized by scanning electron microscope(SEM), photocurrent-voltage(I-V), cyclic voltammetry(C-V), and Impedance measurement. We confirmed that the efficiency of the DSSC increased from 1.92% to 3.25% as the amount of MWCNT increased from 0.01g to 0.06g. In addition, we expected that the catalytic activity and CE resistance of the MWCNT employed CE would show the similar values to those of conventional Pt employed CE.
