| 英文摘要 | poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (pedot:pss) counter electrodes, doped with polyethylene glycol (peg) and acetylene black as binding and conductivity promoting agent, were prepared by a simple mixing method for dye-sensitized solar cell. the electrochemical properties of the electrodes were characterized by cyclic voltammetry, electrochemical impedance spectroscopy (eis), and tafel polarization curves. using peg dopant, the electrocatalytic activity of pedot:pss electrode was much improved, and further improved by adding a small amount of conducting acetylene black (0.2 wt%). the dssc cells, using the pedot:pss electrode with peg (5 wt%) dopant and the composite electrode with peg (5 wt%)/acetylene black, exhibited an energy conversion efficiency of 3.57 and 4.39 %, comparable with 4.50 % of the commonly used pt electrode under the same experimental conditions. these results demonstrate that peg-modified pedot:pss counter electrode is promising to replace the expensive pt for low cost dssc, especially to meet the large-scale fabrication demands. |
