제목 Influence of Cationic Species on Interfacial and Bulk Properties in Dye-Sensitized Solar Cells Employing Solid-State Polymer Electrolyte
초록 Since the concept of dye-sensitized solar cells (DSSCs) was presented, DSSCs have engaged great interests due to their attractive features of high energy-conversion efficiency and low production cost. Dye-sensitized sollar cells (DSSCs) using solid state polymer electrolyte have several advantages such as no solvent leakage and evaporation. However, detailed behavior in the solid-state polymer electrolyte such as charge transfer, interfacial properties and interaction among electrolyte compounds were still not researched intensely compared to the liquid electrolyte system. In this study, we demonstrate the effect of different cations (Li+, Na+, K+ and PMI+) on electron transport properties in DSSCs. Photovoltaic performances of DSSCs were changed differently according to the cation species. Electron lifetime and diffusion coefficient were measured by IMPS/IMVS. And the electrochemical impedance spectroscopy (EIS) was used to study interfacial behavior.
