| Abstract |
Conjugated polymers with 2-{3-[4,6-bis-(4-hexyl-thiophen-2-yl)-pyrimidin-2-yl]-phenyl}-thiazolo[5,4-b]pyridine (mPTP) were synthesized by Stille polymerization for organic solar cells. Synthesized polymers, mPTPBDT-EH, mPTPBDTT-EH and mPTPTTI, contained benzo[1,2-b;3,4-b’]dithiophene (BDT) or 4,8-bis(5-thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene (BDTT) or 6-(2-thienyl)-4H-thieno[3,2-b]indole (TTI) as electron pushing group and mPTP as electron pulling group. The device comprising mPTPBDT-EH showed a VOC of 0.56 V, a JSC of 2.64 mA/cm2, and a FF of 0.30, giving a PCE of 0.44%. The device comprising mPTPBDTT-EH showed a VOC of 0.44 V, a JSC of 2.45 mA/cm2, and a FF of 0.29, giving a PCE of 0.31%. The device comprising mPTPTTI showed a VOC of 0.72 V, a JSC of 4.95 mA/cm2, and a FF of 0.32, giving a PCE of 1.15%.
