제목 Photovoltaic Performances of Dye-Sensitized Solar Cells assembled with Porous Membrane  
초록 Photoelectrochemical solar cell based on nanostructured dye-sensitized TiO2 has been considered as an alternative to a conventional silicon solar cell because of low cost and high conversion efficiency.  It consists of a dye-sensitized nanoparticulated TiO2 electrode, an electrolyte containing redox couple and a Pt coated counter electrode.  Such solar cells have impressive conversion efficiencies reaching around 10 %, where the electrolyte usually used in the cell is an I-/I3- redox couple in organic solvents.  However, the long-term durability of the cell is limited by the leakage or evaporation of the liquid electrolyte.  Therefore a significant effort is taken in order to replace the liquid electrolyte by a gel polymer electrolyte or a solid polymer electrolyte.    In our work, a porous membrane was prepared with the copolymer by a phase-inversion method, and gel polymer electrolyte was prepared by soaking the porous membrane in electrolyte solution containing I-/I3- redox couple.    In this study, we report on the assembling and performance of a dye-sensitized solar cell (DSSC) assembled with the porous gellable membrane.
