    Clean energy sources bring environmental and health benefits by reducing traditional electricity sources. Millstein et al. analyse data from 2007–2015 on the expansion of solar and wind power in the US to explore impacts in terms of air pollution, avoided emissions and associated premature mortality.

    Various strategies are developed to combine high efficiency and stability in perovskite solar cells. Here, Wang et al. mix 2D and 3D mixed-cation and mixed-halide perovskite phases in solar cells with stabilized efficiencies up to 19.5% and improved stability under full illumination and ambient air.

    Electricity storage will benefit from both R&D and deployment policy. This study shows that a dedicated programme of R&D spending in emerging technologies should be developed in parallel to improve safety and reduce overall costs, and in order to maximize the general benefit for the system.

    Metal dichalcogenides are promising electrocatalysts for hydrogen evolution, but more active and stable materials are desired. Here the authors demonstrate that H-TaS2 and H-NbS2 possess high basal-plane activity that increases with cycling through changes in the morphology of the catalysts.

    The Li–O2 cell performance is largely limited by the insulating and insoluble nature of Li2O2. Here the authors report that dual mediators decouple the electrochemical reactions at the cathode from the formation and decomposition of Li2O2 from solutions, helping stabilize the carbon cathode.

The various wavelengths of the solar spectrum can be exploited for different functionalities. Davy et al. develop an organic solar cell that harvests near-ultraviolet photons to power an electrochromic device that controls how many photons go through a smart window in other wavelength ranges, adjusting both visible light and heat ingress.

See Davy et al. 2, 17104 (2017) and News and Views by Delia Milliron, article 17116.
