A new donor-acceptor copolymer, containing benzodithiophene (BDT) and methyl thiophene-3-carboxylate (3MT) units, is designed and synthesized for polymer solar cells (PSCs). The 3MT unit is used as an electron acceptor unit in this copolymer to provide a lower highest occupied molecular orbital (HOMO) level for obtaining polymer solar cells with a higher open-circuit voltage (VOC). The resulting bulk heterojunction PSC made of the copolymer and [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) exhibits a power conversion efficiency (PCE) up to 4.52%, a short circuit current (JSC) of 10.5 mA · cm-(2), and a VOC of 0.86 V.
设计并合成了一种含苯并二噻吩（BDT）和甲基噻吩-3-羧酸甲酯（3MT）单元的新型给体-受体共聚物，用于聚合物太阳能电池（PSC）。在该共聚物中，3MT单元用作电子受体单元，以提供较低的最高占据分子轨道（HOMO）能级，从而获得具有较高开路电压（VOC）的聚合物太阳能电池。由该共聚物和[6,6]-苯基-C71-丁酸甲酯（PC71BM）制成的体异质结PSC表现出高达4.52%的功率转换效率（PCE）、10.5 mA·cm⁻²的短路电流（JSC）和0.86 V的VOC。
