研究了四种基于二氢吡咯并吲哚二酮的有机半导体聚合物在晶体管和光伏电池器件中的性能。二氢吡咯并吲哚二酮单元与苯基、噻吩和联噻吩共聚单体交替共聚，所得聚合物表现出宽吸收、低带隙和深能级，电荷载流子迁移率接近0.1 cm 2 V−1 s−1。在印刷友好溶剂（间二甲苯）中处理的太阳能电池表现出> 2%PCE，具有0.62的高填充因子和0.75V的Voc。
A series of four dihydropyrroloindoledione-based organic semi-conducting polymers are examined for performance in transistor and photovoltaic cell devices. The dihydropyrroloindoledione unit was alternately copolymerized with phenyl, thiophene and bithiophene comonomers, and the resultant polymers exhibit broad absorption, low-bandgaps and deep energy levels, with charge carrier mobilities approaching 0.1 cm2 V−1 s−1. Solar cells processed in a printing friendly solvent (m-xylene) exhibited >2% PCE with a high fill-factor of 0.62 and Voc of 0.75 V.
