Long-term stability is an essential requirement for perovskite solar cells (PSCs) to be commercially viable. Heterojunctions built by low-dimensional and three-dimensional perovskites (1D/3D or 2D/3D) help to improve the stability of PSCs. However, the insulated organic cations of low-dimensional perovskite impede the transport of carriers, decreasing the power conversion efficiency (PCE) of PSCs. Herein, we introduce an in situ cross-linking polymerizable propargylammonium (PA+) to the 3D perovskite film at surfaces and grain boundaries to form a 1D/3D perovskite heterostructure. This passivation strategy not only significantly improves the interfacial carrier transport but also releases residual tensile strain in perovskite films. As a result, the corresponding devices achieve a champion PCE of 21.19%, while maintaining 93% of their initial efficiency after 3055 h of continuous illumination under maximum power point (MPP) operating conditions.

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
