Three tertiary amine dyes (TD01, TD02, and TD03) have been designed and synthesized for the dye sensitized solar cell (DSSC) application. These new dyes TD01, TD02, and TD03 carry different number (one, two, and three, respectively) of donor-π-acceptor units, which are connected together with a central bridgehead nitrogen through oxyethyl linkers. After fabricating the solar cells using these sensitizers and investigating their photovoltaic performances, it was found that the DSSC based on TD03 sensitizer exhibited the best power conversion efficiency of 5.91%. The higher performance of TD03 compared to TD01 and TD02 sensitizers is attributed to its superior short-circuit current density and high open-circuit voltage resulted from the presence of tertiary anchoring and oxyethyl moieties, respectively.

具有多个供体π受体分支的桥头氮三脚架有机染料用于太阳能电池

已经设计并合成了三种叔胺染料(TD01TD02TD03)用于染料敏化太阳能电池(DSSC)应用。这些新染料TD01TD02TD03带有不同数目(分别为一个,两个和三个)供体-π-受体单元,它们通过氧乙基接头与中央桥头氮连接在一起。在使用这些敏化剂制造太阳能电池并研究了它们的光伏性能后,发现基于TD03敏化剂的DSSC表现出5.91%的最佳功率转换效率。TD03TD01更高的性能TD02TD02敏化剂分别由于叔锚固和氧乙基部分的存在而具有优异的短路电流密度和高开路电压。
