In this device, ZnO was used as the electron extraction layer, which was coated with ethoxylated polyethylenimine (PEIE) for smoothen the ZnO surface. Open circuit voltage of this OPV can be as high as 1.36 eV, which is close to the theoretical limit of SubPc-based device. © 2015 JSAP.[SDGs]SDG7Boron; Flat panel displays; Heterojunctions; II-VI semiconductors; Open circuit voltage; Oxide minerals; Thin film transistors; Timing circuits; Zinc oxide; Electron extraction; Organic photovoltaic devices; Polyethylenimines; Subphthalocyanines; Theoretical limits; ZnO surface; Organic solar cellsconference paper10.1109/AM-FPD.2015.71732362-s2.0-84947922537https://www.scopus.com/inward/record.uri?eid=2-s2.0-84947922537&doi=10.1109%2fAM-FPD.2015.7173236&partnerID=40&md5=4fe1aab0cde853bed576333f386088c5
