摘　　要：High performance Pt counter electrode is prepared by using vacuum thermal decomposition at a relatively low (120℃) temperature on a flexible polyethylene naphthalate substrate coated with indium-doped tin oxide for use in flexible dye-sensitized solar cells.The obtained Pt counter electrode shows a good chemical stability,high light transmittance,and high electrocatalytic activity for the I3-/I-redox reaction.The energy conversion efficiency of a flexible dye-sensitized solar cell based on the prepared Pt counter electrode and a TiO 2 /Ti photoanode reaches 5.14% under a simulated solar light irradiation with intensity of 100 mW cm-2.High performance Pt counter electrode is prepared by using vacuum thermal decomposition at a relatively low （120℃） temperature on a flexible polyethylene naphthalate substrate coated with indium-doped tin oxide for use in flexible dye-sensitized solar cells. The obtained Pt counter electrode shows a good chemical stability, high light transmittance, and high electrocatalytic activity for the I3/l- redox reaction. The energy conversion efficiency of a flexible dye-sensitized solar cell based on the prepared Pt counter electrode and a TiO2/Ti photoanode reaches 5.14% under a simulated solar light irradiation with intensity of 100 mW cm-2.
