Abstract |
Bulk heterojunction polymer solar cells (PSCs) have been considered ideal for application in large-area flexible devices fabricated via low-cost practical solution processes such as spin-coating, ink-jet, and roll-to-roll printing techniques. Among many kinds of conjugated polymers, random terpolymers have emerged as promising materials with many advantages over electron-donating binary copolymers owing to the ability to fine-tune the internal morphology of the active layer, solubility, absorption range, energy levels, and polymer chain orientation of the former in blend films. In this work, a new conjugated terpolymers based on 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene as the electron-donating unit, methyl-3-thiophenecarboxylate (3MT) as the weak electron-accepting unit, and benzo[c][1,2,5]thiadiazole (BTz) or 5,50-bis(2-ethylhexyl)-4H,4’H-1,10-bithieno[3,4-c]pyrrole-4,4’,6,6’(5H,5’H)-tetraone (BiTPD) as the electron-accepting unit stronger than 3MT were synthesized to investigate the effect of the BTz or BiTPD unit on their optical and electrochemical properties and the performance of the derived non-fullerene PSC devices. |
