Novel organic pyridinium ylide sensitizers (NO109–111) consisting of various anchoring groups were synthesized and characterized for applications in dye sensitized solar cells. Compared with the pyridine-N-oxide dye (NO108), the ylide sensitizers with strong electron-withdrawing acceptors exhibited dominant ultraviolet absorption properties and efficient binding abilities to the TiO₂ surface. Among these dyes, the pyridinium ylide NO111 sensitized solar cell showed the highest efficiency (5.15%), which was improved to 7.41% by employing coadsorbent chenodeoxycholic acid.

用于染料敏化太阳能电池的新型吡啶鎓吡啶染料

合成了由各种锚定基团组成的新型有机吡啶鎓内鎓盐敏化剂（NO109-111），并对其进行了表征，以用于染料敏化太阳能电池。与吡啶-N-氧化物染料（NO108）相比，具有强吸电子受体的叶立德敏化剂表现出显着的紫外线吸收特性和对TiO ₂表面的有效结合能力。在这些染料中，吡啶鎓叶立德NO111敏化太阳能电池显示出最高效率（5.15％），通过使用共吸附性鹅去氧胆酸将其提高到7.41％。
