A new alternating copolymer of dithienosilole and thienopyrrole-4,6-dione (PDTSTPD) possesses both a low optical bandgap (1.73 eV) and a deep highest occupied molecular orbital energy level (5.57 eV). The introduction of branched alkyl chains to the dithienosilole unit was found to be critical for the improvement of the polymer solubility. When blended with PC(71)BM, PDTSTPD exhibited a power conversion efficiency of 7.3% on the photovoltaic devices with an active area of 1 cm(2).
一种新的二噻吩并[3,2-b:2',3'-d]噻吩并[3,4-b]吡咯-4,6-二酮（PDTSTPD）与噻吩并吡咯-4,6-二酮（PDTSTPD）交替共聚的聚合物具有较低的光学带隙（1.73eV）和深的最高占据分子轨道能级（5.57eV）。研究发现，在二噻吩并噻吩单元中引入支化烷基链对于提高聚合物的溶解性至关重要。当与 PC(71)BM 共混时，PDTSTPD 在活性面积为 1cm(2)的光伏器件中表现出 7.3%的功率转换效率。
