英文摘要Inverted (p-i-n) perovskite solar cells (PerSCs) have attracted much attention owing to their low temper -ature processability, less hysteresis effect and easy integration as a subunit for the tandem device. The unsatisfactory interface contacts and energy level barrier between adjacent interlayers on the cathode side are one of the key challenges for the development of p-i-n PerSCs. Herein, perylene diimide-based (PDI) ionene polymer was synthesized and developed as a cathode interlayer (CIL) to enhance interface contact, reduce the energy level barrier and prevent the migration of I-ions. The compact PNPDI CIL with high conductivity and appropriate lowest unoccupied molecular orbital (LUMO) level, resulted in a high efficiency device (20.03%), which is higher than the control device with bathophenan-throline (Bphen) (19.48%). Bphen-based CIL shows better adjusting ability of the work function of cathode metal but exhibits poor film-forming property. So, the synergistic effect of 1 + 1 > 2 can be obtained by combining Bphen and PNPDI into one CIL. As expected, the device performance was further improved by using the mixed CIL of Bphen and PNPDI, and 21.46% power conversion efficiency (PCE) was achieved. What's more, the compact and hydrophobic mixed CIL dramatically enhanced the resistance to I-ions and moisture, which led to much enhanced device stability.(c) 2023 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
