Ampere-hour-scale zinc–air pouch cells

Nature Energy, Published online: 12 April 2021; doi:10.1038/s41560-021-00807-8Zinc–air batteries are viewed as a sustainable storage technology, but their commercialization requires a genuine performance leap forwards from the laboratory scale. Here the authors report a cell-level design and demonstrate an ampere-hour pouch cell with exceptionally high...

Design rules for high-efficiency both-sides-contacted silicon solar cells with balanced charge carrier transport and recombination losses

Nature Energy, Published online: 12 April 2021; doi:10.1038/s41560-021-00805-wFront- and back-junction silicon photovoltaics dominate the market thanks to a lower manufacturing complexity compared with that of other device designs yet advances in efficiency remain elusive. Richter et al. now present an optimized design for the front and back junctions...

Stabilization of formamidinium lead triiodide α-phase with isopropylammonium chloride for perovskite solar cells

Nature Energy, Published online: 08 April 2021; doi:10.1038/s41560-021-00802-zThe operational stability of formamidinium lead triiodide solar cells varies with the fabrication method of the perovskite layer. Now Park et al. find that isopropylammonium stabilizes the perovskite structure and leads to solar cells with 2,000-h stability under constant...

Linking solar and wind power in eastern Africa with operation of the Grand Ethiopian Renaissance Dam

Nature Energy, Published online: 08 April 2021; doi:10.1038/s41560-021-00799-5The Grand Ethiopian Renaissance Dam will be hugely beneficial to Ethiopia, but has raised tensions with neighbouring countries that rely on flow from the Blue Nile. Sterl et al. present scenarios for dam operation coupled with solar and wind power generation that could mitigate...

Guided by metal–substrate bonding

Nature Energy, Published online: 05 April 2021; doi:10.1038/s41560-021-00808-7The development of metallic anodes for next-generation high-energy batteries is largely hindered by dendritic growth issues. Now, an interface between metals and substrates is engineered to facilitate their strong chemical bonding, leading to uniform metal deposition and high...

Regulating electrodeposition morphology in high-capacity aluminium and zinc battery anodes using interfacial metal–substrate bonding

Nature Energy, Published online: 05 April 2021; doi:10.1038/s41560-021-00797-7Using metal anodes could in principle boost the energy density of batteries but their electrodeposition often negatively impacts battery performance. Here the authors propose an oxygen-mediated metal–substrate bonding strategy to regulate metal deposition and demonstrate highly...
