In this study, fullerene-contained double-cable conjugated polymers were successfully constructed using the functionalization-polymerization method. The power conversion efficiencies were increased by enhancing the fullerene contents. These conjugated polymers with molecular heterojunction show potential application in organic electronic devices.
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.
