Recently, tremendous developments in polymer solar cells(PSC) have intrigued researcher to study new conjugated materials. In our research, we synthesize new type of electron donor material with long linear alkyl chain for PSCs. This new type of donor material has simple chemistry for synthesis. It has strong intramolecular interaction, so can make more planer structure and ensure long conjugation length. And long linear alkyl chain in our material guarantee sufficient solubility, crystallinity, and good phase separation. In this presentation, We made polymers with 4,7-bis(2-thenyl)-2,1,3-benzothialzole and introduced different length of alkyl chain. We analyze alkyl chain effect of optical and electrical properties |
