Isoindigo, as a new electron acceptor unit for organic electronic materials, was integrated into two low-energy gap oligothiophenes. Optical and electrochemical studies of the newly synthesized oligomers demonstrate broad absorption through the visible spectrum, along with appropriate energy levels, as desired for light harvesting donors for organic solar cells when blended with [6,6]-phenyl-C(61)-butyric acid methyl ester (PC(60)BM). Molecular heterojunction solar cells were fabricated using these oligomers and exhibit a power conversion efficiency up to 1.76% with a V(oc) of 0.74 V, I(sc) of 6.3 mA/cm(2) and fill factor of 0.38.
异吲哚作为一种新的电子受体单元被整合到两个低能隙的寡聚噻吩中。新合成的寡聚物的光学和电化学研究表明，它们在可见光谱范围内具有广泛的吸收，同时具有适当的能级，当与[6,6]-苯基-C（61）-丁酸甲酯（PC（60）BM）共混时，适合作为有机太阳能电池的光收集给体。使用这些寡聚物制备了分子异质结太阳能电池，其能量转换效率高达 1.76%，开路电压为 0.74V，短路电流为 6.3mA/cm(2)，填充因子为 0.38。
