| 中文摘要:利用市售联吡啶钌染料 TG6 为敏化剂制备染料敏化太阳能电池, 引入鹅去氧胆酸 (CDCA) 为共吸附剂优化
电池的光伏性能。实验结果表明, 当 TG6 浓度为 0.3 mmol/L, 共吸附剂 CDCA 浓度为 10 mmol/L 时, 以 TG6 敏化的
太阳能电池的光电转换效率为 4.64%, 比未优化的同类电池提高了 23%。电化学阻抗分析表明 CDCA 的引入, 使染
料/二氧化钛/电解液界面的回传电阻提升了近 50%, 有效提升了光生电子寿命, 实现了抑制光生电子复合的目的。 |

| Abstract:Dye sensitized solar cells were fabricated with bipyridine ruthenium dye TG6 as photo sensitizer. The photovoltaic performance was further optimized using chenodeoxycholic acid (CDCA) as co-adsorbent during fabrication process. The results show
than an optimized photoelectric conversion efficiency of 4.64%, which is an increment of 23% with respect to homogeneous without
co-adsorbent was achieved when the concentration of TG6 and CDCA was selected as 10 mmol/L and 0.3 mmol/L, respectively. The
electrochemical impedance analysis showed that the charge resistance between dye/titanium dioxide/electrolyte interface is significant
enhanced by nearly 50% with assistant of CDCA, thus effectively improved photogenerated electron lifetime and suppressed recombination process. |
