设计并合成了新型可溶性芴-噻吩共轭齐聚物FT6CE,对该化合物的热性质、光物理性质和电化学性质进行了详细表征.以FT6CE为给体,(6,6)-苯基-C61-丁酸甲酯(PC61BM)为受体,用溶液旋涂方法制备了体异质结太阳能电池器件,发现采用体积比为2∶1的氯仿/氯苯混合溶剂制备的器件性能最好,能量转换效率达到2.15%.
Soluble narrow bandgap fluorene-thiophene conjugated oligomer FT6CE was designed and synthesized, and its thermal, photophysical and electrochemical properties were investigated. Bulk heterojunction (BHJ) solar cells with FT6CE and PC61BM as electron donor and acceptor, respectively, were fabricated by spin casting. Maximum power conversion efficiency (PCE) of 2.15% was realized by using chloroform/chlorobenzene with a volume ratio of 2; 1 as the processing solvent.
