Carbon nanotube-Platinum (CNTs-Pt) were deposited on conducting FTO-glass substrate for counter electrode application in dye-sensitized solar cells (DSCs) by doctor blade and annealing at 300oC for 30 min. Electrochemical impedance measurement shows that charge transfer resistance of CNTs-Pt in liquid electrolyte is 1.10 Ωcm2, which is higher than that of 0.72 Ωcm2 for Pt-sputtered and less than that of 4.59 Ωcm2 for CNTs as counter electrode of DSC. Furthermore, the DSCs with CNTs-Pt electrode exhibited high energy conversion efficiency of 7.86(±0.05) %, which was higher than 6.02(±0.12) % for CNTs and less than 8.66(±0.06) for Pt-sputtered electrode. |
