Herein, we introduce a self-assembled fullerene (C60-SAM) interlayer at this interface, with a large monovalent organic cation incorporated. We find this enhances the surface conductivity of the ETL, mitigates interface recombination, and reduces the energetic mismatch with the overlying perovskite. At the device level, this results in efficient electron extraction and suppressed device hysteresis, substantiated by drift-diffusion simulations. The combination of these improvements led to hysteresis-free n-i-p perovskite/silicon tandem solar cells on textured silicon with an efficiency of 27% (over 1 cm2) and an open-circuit voltage reaching 1.9 V.enginfo:eu-repo/semantics/openAccessTarımsal BilimlerZiraatTarım MakineleriTarımda EnerjiBiyoyakıt TeknolojisiKimyaTemel BilimlerMühendislik ve TeknolojiAgricultural SciencesAgricultureFarm MachineryEnergy in AgricultureBiofuels TechnologyChemistryNatural SciencesEngineering and TechnologyMühendislik Bilişim Ve Teknoloji (Eng)Temel Bilimler (Sci)MühendislikMalzeme BilimiEnerji Ve YakıtlarMalzeme Bilimi ÇokdisiplinliEngineering Computing & Technology (Eng)Natural Sciences (Sci)EngineeringMaterials ScienceEnergy & FuelsMaterials Science MultidisciplinaryKimya (çeşitli)Fizik BilimleriYenilenebilir Enerji, Sürdürülebilirlik ve ÇevreYakıt TeknolojisiEnerji Mühendisliği ve Güç TeknolojisiMalzeme KimyasıChemistry (miscellaneous)Physical SciencesRenewable Energy, Sustainability and the EnvironmentFuel TechnologyEnergy Engineering and Power TechnologyMaterials Chemistryarticle4633464410.1021/acsenergylett.4c01841
