摘要

Recent research studies have shown that the halogenated benzo[1,2-b:4,5-b′]dithiophene (DTBDT unit as a polymer donor exhibits high charge carrier mobility due to the well-ordered molecular packing and high crystallinity, which is meaningful for achieving highly efficient organic solar cells (OSCs.
