Tunable Nanoporous Network Polymer Nanocomposites having Size-Selective Ion Transfer for Dye-sensitized Solar Cells |
| 초록 |
We present the selective ion transfer by tunable nanoporous network polymer membrane nanocomposites and the effect of pore sizes in the nanocomposites on diffusion of triiodide. The nanoporous network polymer membrane having different pore sizes were grown on the surfaces of dye-sensitized nanocrystalline TiO2 particles via the surface-induced cross-linking polymerization. These porous layers modulated interfacial electron transfer associated with I– and I3–, revealed using transient absorption spectroscopy (TAS) and electrochemical impedance spectroscopy (EIS). This novel concept has been extended to a quasi-solid state DSC, which exhibited long-term stability and excellent power conversion efficiency at an elevated temperature. |
