a Device structure of the ultrathin solar cells and chemical structure of the nonfullerene active layer; A Zn2+-chelated polyethylenimine (PEI-Zn) is developed as the electron-transporting layer (ETL). b Pictures of the fabricated ultrathin OSCs; the picture on the right is a cell attached on the wrist. c, d J-V characteristics of the ultrathin devices with conducting polymer (PEDOT:PSS) or Ag nanowires as the transparent electrodes. Two different nonfullerene active layers of PBDB-T-2F:IT-4F and PBDB-T-2F:Y6 were used in the ultraflexible OSCs.
