Abstract Organic solar cells have recently attracted attention because of their advanced properties including low expense, light-weight, mechanical flexibility, simple processability and large-scale production. We synthesized conjugated polymers composed of PTTICN, PTTICNR and PTTIFR based on TTI, 2-fluoropyrimidine and 2-pyriminecarbonitrile. The optical band gaps of PTTICN, PTTICNR and PTTIFR were about 2.0 eV. The synthesized polymers (PTTICN, PTTICNR and PTTIFR) showed deep HOMO energy levels between -5.26 and -5.34 eV. The device based on PTTICN and PC71BM (1:4) with DIO showed a VOC of 0.82 V, a JSC of 6.38 mA/cm2, and a fill factor (FF) of 0.54, having a power conversion efficiency(PCE) of 2.81%. The device based on PTTICNR and PC71BM (1:4) with DIO exhibited a VOC of 0.81 V, a JSC of 6.38 mA/cm2, and a FF of 0.43, having a power conversion efficiency(PCE) of 2.22%. The device based on PTTIF and PC71BM (1:4) with DIO exhibited a VOC of 0.64 V, a JSC of 7.38 mA/cm2, and a FF of 0.55, having a power conversion efficiency(PCE) of 2.61%.
