合成了一种具有强电子给体吲哚-三苯胺的简单无金属给体-受体型增敏剂U01，用于tio2纳米晶薄膜的全色增敏。由于具有强电子供体和坚固的结构，U01的光电性能显著增强。新型U01敏化太阳能电池具有良好的光伏性能：短路光电流密度（Jsc）为10.70 mA cm−2，开路光电压（Voc）为0.758 V，填充因子（FF）为0.74，在标准全局AM 1.5太阳光照条件下，总转换效率为6.01%。我们的研究结果表明，基于吲哚-三苯胺的稳健的D-A分子结构是一类非常有前途的全色增敏剂，可以改善染料敏化太阳能电池（dsc）的性能。
A simple metal-free donor–acceptor type sensitizer U01, bearing strong electron donor indoline-triphenylamine was synthesized for panchromatic sensitization of TiO2nanocrystalline film. Photovoltaic properties of U01 showed remarkably enhanced light harvesting due to the presence of strong electron donor and robust structure. The new U01 sensitized solar cell exhibited a photovoltaic performance: a short-circuit photocurrent density (Jsc) of 10.70 mA cm−2, an open-circuit photovoltage (Voc) of 0.758 V and a fill factor (FF) of 0.74, corresponding to an overall conversion efficiency of 6.01% under standard global AM 1.5 solar light condition. Our results suggest that indoline-triphenylamine based robust D–A molecular architecture is a highly promising class of panchromatic sensitizers for improvement of the performance of dye-sensitized solar cells (DSCs).
