초록
Dye-sensitized solar cell (DSC) consist of oxidation semiconduction electrode, electrolyte and counter electrode. Among these, Pt as counter electrode of DSC plays a role in helping redox reaction of iodine ions in electrolyte, also, transferring electrons into electrolyte. In this case, it is expected that characteristics of Pt electrodes strongly depend on fabrication process and its surface condition. In this study, electrochemical behavior of the electro-plated Pt electrode was compared with that of the sputtered Pt electrode, using cyclic-voltammetry and impedance spectroscopy (PARSTATE 2273, by AMETEK). Surface morphology of Pt electrode was investigated by AFM (XE-100, by PSIA). As a result, it was considered that electrochemical properties of sputtered Pt electrode is superior to that of electro-plated Pt electrode.
