In recent years, bulk hetero-junction organic solar cells have been studied because lightweight, low-cost, solution-processability and flexibility. In this literature, our group demonstrate strong electron withdrawing units on an electron-deficient backbone based on 1,4-dibromotetrafluorobenzene unit. Recently our group has synthesized a copolymer which exhibit strong electron-withdrawing character, a planar architecture, and high solubility. In this work, tetrafluorophenylene unit was used in order to construct copolymers for organic photovoltaics and it exhibited large electron and hole mobilities. Tetrafluorophenlene unit has more advantage of decreasing steric encumberance than other acceptor units. Benzodithiophene (BDT) and dithieno-benzodithiophene (BDTT) were selected here as the initial donor monomers because those have high solubilizing characteristics, low-bandgap. Moreover, the fluorine affects morphology resulting blends of polymer donors and fullerene acceptors that are regarded as key requisite determining the PCE of the OPV devices. In conclusion, this polymer that have highest performance showed VOC of 0.75 V, a JSC of 11.80 mA/cm2, and FF of 0.59, giving the PCE 5.22%.
