Thieno[3,2-b]thiophene-based conjugated polyfluorene copolymer for efficient polymer solar cell.
We have synthesized and characterized a polyfluorene derivative composed of octyl-substituted thieno[3,2,-b]thiophene and 2,1,3-benzothiadiazole as an acceptor unit. The best power conversion efficiencies of the polymer were showed with 1.63% and 2.31% by using PCBM and PC71BM, respectively.
