제목 Effects of Metal Oxide Nanoparticles on PEO Based Composite Polymer Electrolyte in Solid State Dye-Sensitized Solar Cells
초록 Solid state dye-sensitized solar cells (DSSCs) employing polymer electrolyte have exhibited lower energy conversion efficiency, compared to liquid state DSSCs, mostly due to low ionic conductivity. In this study, metal oxide nanoparticles (TiO2, Al2O3 etc.) were incorporated into polymer-oligomer blend electrolytes to improve the ionic conductivity and consequently the energy conversion efficiency. Interestingly, photovoltaic performances of solid state DSSCs changes differently depending on the type of metal oxide nanoparticles. Effects of metal oxide nanoparticles on the improved performance were characterized by interfacial and ionic transport behavior, in particular electron recombination and diffusion of ions by electrochemical impedance spectroscopy (EIS) and polymer crystallinity upon the addition of metal oxide nanoparticles by differential scanning calorimetry (DSC).
