The industrialization of polymer solar cells (PSCs) will require high-performance devices with high efficiencies and stabilities. Although high-performance PSCs have been achieved owing to outstanding research into their component materials and device structures, several challenges still need to be overcome, including the synthetic complexity of producing the active material. In this study, donor polymers based on two heterocyclic rings and simple donor–acceptor structures are designed in order to obtain a low-cost material for PSCs. An inexpensive and high-performance donor polymer is realized by the introduction of a functional group substitution. It has lower synthetic complexity than commercial donor polymers, and many advantages such as high overall yield, low number of synthetic steps, and inexpensive raw materials. |
