In this work, the "functionalization-polymerization" (FP) method has been used to construct fullerene-contained double-cable conjugated polymers with "donor-acceptor" backbones. It was realized via synthesizing a fullerene-contained monomer and performing Stille polymerization. With this method, a series of double-cable conjugated polymers with different fullerene contents were developed and applied into single-component organic solar cells. The power conversion efficiencies (PCEs) based on these polymers increased from 0.71% to 1.71% with the enhanced fullerene contents. The relatively low PCEs might be originated from the poor microstructure in these polymers. These new conjugated polymers with molecular heterojunction would show potential application in organic electronic devices. [ABSTRACT FROM AUTHOR]
