Herein, we synthesized a new copolymer PM6 based on 4,8-bis(5-(2-ethylhexyl)-4-fluorothiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene(BDT-F) and 1,3-bis(thiophen-2-yl)-5,7-bis(2-ethylhexyl)benzo-[1,2-c:4,5-c’]dithiophene-4,8-dione (BDD). The optical, electrochem., and photovoltaic properties, the mol. packing pattern, and the morphol. of the blend lms were investigated. Compared with the nonfluorinated derivative PBDTBDD, PM6 exhibited a similar optical bandgap of 1.80 eV and a deeper HOMO level of -5.45 eV (-5.25 eV for PBDTBDD), which is beneficial for a high Voc. BHJ PSCs based on PM6/PC71 BM with both conventional and inverted device structures were fabricated and showed promising photovoltaic performance: a high Voc of 0.98 V and a PCE of 8% for the conventional devices and up to 9.2% for the inverted devices. Furthermore, the PM6/PC71BM based semitransparent device exhibited a PCE of 5.7%, which is among the highest values obtained for a semitransparent single-junction device. In addition, we found that the neat film of PM6 exhibited strong crystallinity and a dominant face on packing with respect to the electrodes, which is advantageous for charge transport. These results indicate that PM6 is a promising material for photovoltaic application.
