(PTCDA). The results showed that the -CN group played an important role in increasing short circuit current density (I sc) and power conversion efficiency (PCE). Both rigid device glass-ITO/4T-CN/PTCDA/Al and flexible device PET-ITO (indium tin oxides coated with polyethylene terephthalate)/4T-CN/PTCDA/Al had greater I sc and PCE compared with rigid device glass-ITO/4T/PTCDA/Al. It was possible that the
摘要 为开发具有良好性能特性的新型光伏材料和有机光伏器件,5-cyano-2,2':5',2"-terthiophene (3T-CN)和5-cyano-2,2':5合成了',2":5",2"'-四噻吩(4T-CN)。3T-CN 和 4T-CN 是具有介晶特性的供体-受体寡噻吩衍生物。研究了3T-CN和4T-CN的光伏性能。使用 3T-CN、4T-CN 和 3,4,9,10-苝四羧酸二酐 (PTCDA) 制造刚性和柔性光伏器件。结果表明,-CN基团在提高短路电流密度(I sc)和功率转换效率(PCE)方面发挥了重要作用。与刚性器件玻璃-ITO 相比,刚性器件玻璃-ITO/4T-CN/PTCDA/Al 和柔性器件 PET-ITO(涂有聚对苯二甲酸乙二醇酯的氧化铟锡)/4T-CN/PTCDA/Al 具有更高的 I sc 和 PCE /4T/PTCDA/铝。具有强吸电子特性的-CN基团和4T-C
