Elimination of interfacial charge accumulation and inhibition of ion migration are still challenging for promoting both efficiency and operational stability of perovskite solar cells (PVSCs) with 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)-9,9′-spiro bifluorene (spiro-OMeTAD). Here an innovative interface engineering, self-assembled cocrystal layer (SAM-CL) for PVSCs is constructed from a 1-pyrenemethylamine hydrochloride (PRMA) monolayer on the perovskite surface and 2,3,5,6-tetrafluoro-7,7′,8,8′-tetracyanoquinodimethane (F4TCNQ) doped in spiro-OMeTAD through intermolecular π–π interactions and hydrogen bonds. SAM-CL optimizes interfacial energy level alignment by a strong charge-transfer effect, thereby eliminating interfacial charge accumulation. Moreover, the excellent barrier effect of large pyrene rings and fluorine atoms in SAM-CL effectively hinders ion migration and moisture invasion, thus significantly improving the stability of PVSCs. The resulting PVSCs yield a power conversion efficiency (PCE) of 24.03% with a high open circuit voltage of 1.21 V and deliver impressive stability, which can maintain 85% of initial PCE after over 1800 h in air with a relative humidity of 70–80% without encapsulation.

Energy & Environmental Science

Energy & Environmental Science is an international journal dedicated to publishing exceptionally important and high quality, agenda-setting research tackling the key global and societal challenges of ensuring the provision of energy and protecting our environment for the future. The scope is intentionally broad and the journal recognises the complexity of issues and challenges relating to energy conversion and storage, alternative fuel technologies and environmental science. For work to be published it must be linked to the energy-environment nexus and be of significant general interest to our community-spanning readership. All scales of studies and analysis, from impactful fundamental advances, to interdisciplinary research across the (bio)chemical, (bio/geo)physical sciences and chemical engineering disciplines are welcomed. Topics include, but are not limited to, the following: Solar energy conversion and photovoltaics Solar fuels and artificial photosynthesis Fuel cells Hydrogen storage and (bio) hydrogen production Materials for energy systems Capture, storage and fate of CO2, including chemicals and fuels from CO2 Catalysis for a variety of feedstocks (for example, oil, gas, coal, biomass and synthesis gas) Biofuels and biorefineries Materials in extreme environments Environmental impacts of energy technologies Global atmospheric chemistry and climate change as related to energy systems Water-energy nexus Energy systems and networks Globally applicable principles of energy policy and techno-economics
