摘要
Organic solar cells(OSCs)have attracted huge attention because of their unique merits[1−3].In last few years,thanks to the design of new materials and device engineering,the power conversion efficiencies(PCEs)of OSCs have surpassed 18%[4−8].The PM6:Y6 cells are efficient binary cells,offering high PCEs over 16%[9−11].The high performance originates from the efficient free charge generation and the ground state dipole field at the donor-acceptor interface that promotes the exciton dissociation[12].
