제목 Surface Modification of Platinum Counter Electrode with PEG-thiols and Application to the Dye-Sensitized Solar Cells Employing Polymer Electrolytes
초록 The charge transfer process of the solid polymer electrolyte/Pt counter electrode interface and the diffusion coefficient of triiodide in the electrolyte are important parameters for determining the energy conversion efficiency of DSSCs. Because polymer electrolyte has lower ionic conductivity and diffusion coefficient than liquid electrolyte has. Besides, relatively slow redox reaction is occurred at the interface and polymer electrolyte is less compatible with Pt counter electrode than liquid electrolyte. As a method of improvement of electron transfer and compatibility at the interface, PEG-thiols were introduced as a surface modifier on the Pt counter electrode.
