benzotriazole‐bridged sensitizers are designed and synthesized (BTA‐I and BTA‐II) containing a furan moiety for dye‐sensitized solar cells (DSSCs). Two corresponding dyes (BTA‐III and BTA‐IV) with a thiophene spacer were also synthesized for comparison. All of these dyes performed as sensitizers for DSSCs, and the photovoltaic performance data of these benzotriazole‐bridged dyes showed a high open‐circuit
设计并合成了两种新型的苯并三唑桥连的敏化剂(BTA-I和BTA-II),其中含有呋喃部分,用于染料敏化太阳能电池(DSSC)。还合成了带有噻吩间隔基的两种相应的染料(BTA-III和BTA-IV)用于比较。所有这些染料均作为DSSC的敏化剂,这些苯并三唑桥连染料的光伏性能数据显示出高的开路电压(V oc:804–834 mV)。在四种染料中,具有呋喃部分和支链烷基链的基于BTA-II的DSSC表现出最高的V oc(834 mV),光电流密度(J sc)为12.64mA cm -2,并且填充因子(FF)为0.64,对应于6.72%的总转换效率(η)。最重要的是,证明了BTA-I,BTA-II,BTA-III,BTA-IV型DSSC与离子液体电解质在1000 h光浸泡条件下的长期稳定性,并且BTA-II表现出更好的光伏性能。功率转换效率高达5.06%。
