Synthesis of Organic Sensitizer with Fluorenone as Conjugation Bridge and Its Performance Research

摘要:

设计合成了以芴酮为π-桥基的纯有机光敏染料BFA，并利用高分辨质谱 (HRMS) 、核磁共振氢谱 (1H–NMR) 及核磁共振碳谱 (13C–NMR) 对其结构进行了表征。研究了这个染料的光物理和电化学性质，并将其应用于染料敏化太阳能电池 (DSSCs) 的制作中。在 100 mW/cm2 (AM 1.5) 模拟太阳光的照射下，由其所制作的敏化太阳能电池的光电转换效率为2.51 %；开路电压(Voc)、短路电流密度(Jsc)、填充因子(FF)分别为0.73 V、4.46 mA/cm2 和0.77。

Abstract:

A novel organic dye with fluorenone as ?-conjugation bridge was designed and synthesized as sensitizers for dye sensitized solar cells (DSSCs). The dye was characterized by mass spectrometry (MS), proton nuclear magnetic resonance spectrometry (1H–NMR), and carbon nuclear magnetic resonance spectrometry (13C–NMR). The photophysical and electrochemical properties of the dye were studied. The dye achieved a light to electricity conversion efficiency (η) of 2.51% (open-circuit photovoltage Voc = 0.73 V, short-circuit photocurrent density Jsc = 4.46 mA/cm2 and fill factor FF= 0.77) under 100 mW/cm2 (AM 1.5G).
