英文摘要	the interlayer inserted between active layer and ito has been a key issue for improving electron extraction in inverted polymer solar cells (ipscs), while the ideal interlayer for ipscs has not been well developed. in this work, we presented a spontaneous vertical phase separation (svps) self-assembled bilayers structure with benmelm-ci ionic liquid (il) interfacial bottom layer and a photoactive top layer via a single spin-coated step of benmelm-ci il and organic donor-acceptor composite and achieved a pce as high as 8% based on ipscs with ptb7 as the donor. the presence of benmelm-ci il reduces the work function of ito and leads to a better energy-level matching for efficient charge-transfer. the driving force of svps selfassembled structure is from the relative surface energy difference between organic materials and benmelm-ci ils, together with their interactions with the substrates. this self-assembled process procedure pave the way to simplify the manufacturing of low-cost and large-area organic electronic devices.
