Abstract A new polyelectrolytic polyacetylene, poly(2-ethynyl-N-iodopyridinium triiodide), was applied for DSSCs. Poly(2-ethynyl-N-iodopyridinium triiodide) was prepared by the non-catalyst polymerization of 2-ethynylpyridine using iodine without any additional initiator or catalyst in high yields. The photoluminescence peak was observed at 534 nm corresponding to a photon energy of 2.32 eV. Quasi-solid-state DSSCs with a SnO2:F/TiO2/D719 dye/solid-state electrolyte/Pt device was fabricated with the poly(2-ethynyl-N-iodopyridinium triiodide) electrolyte, which shows the power conversion efficiency (PCE) of 5.79%.

用于准固态染料敏化太阳能电池应用的聚电解质聚乙炔

摘要 一种新型聚电解聚乙炔聚（2-乙炔基-N-碘化吡啶三碘化物）被应用于DSSCs。聚（2-乙炔基-N-碘化吡啶鎓三碘化物）是通过使用碘对 2-乙炔基吡啶进行非催化剂聚合而制备的，无需任何额外的引发剂或催化剂，收率很高。在 534 nm 处观察到光致发光峰，对应于 2.32 eV 的光子能量。具有 SnO2:F/TiO2/D719 染料/固态电解质/Pt 器件的准固态 DSSC 用聚（2-乙炔基-N-碘吡啶三碘化物）电解质制造，显示了功率转换效率（PCE） 5.79%。
