A new low-band gap polymer containing thiophene and cyclopentadiene, poly(5,2,2'-dioctyldithio-phenylcyclopentadiene) (PDTCP), has been synthesized via the FeCl3 oxidative polymerization. PDTCP showed a broad absorption band and a low energy band gap of 1.82 eV. The photoluminescence (PL) of PDTCP is completely quenched upon addition of PCBM indicative of efficient charge transfer. Bulk heterojunction organic photovoltaic cells (OPVs) fabricated from PDTCP as an electron donor showed an open-circuit voltage (V(OC)) of 0.50 V, a short-circuit current (J(SC)) of 1.24 mA/cm2, and the power conversion efficiency of up to 0.20% under AM 1.5 (100 mW/cm2).
通过FeCl3氧化聚合反应合成了一种新型的含噻吩和环戊二烯的低带隙聚合物聚（5,2,2'-二辛基二硫代苯基环戊二烯）（PDTCP）。PDTCP显示出宽吸收带和1.82 eV的低能带隙。加入PCBM后，PDTCP的光致发光（PL）完全猝灭，表明电荷转移效率高。以PDTCP作为电子供体制备的本体异质结有机光伏电池（OPV）在AM 1.5（100 mW/cm2）光照下的开路电压（V(OC)）为0.50 V，短路电流（J(SC)）为1.24 mA/cm2，功率转换效率高达0.20%。
