Damp-proofing perovskites

Perovskite solar cells have recently taken centre stage in photovoltaic research thanks to their high efficiency in converting solar radiation into electricity. However, they are affected by poor stability, partly caused by moisture. Yang et al. now report a water-resistant layer that protects the surface of the perovskite device from moisture in high-humidity environments.

See Yang et al. 1, 15016 (2016).

    High-performance polymer solar cells are normally processed with halogenated solvents, which are toxic and hazardous. Now, high power-conversion efficiency in bulk-heterojunction devices is achieved by using a non-toxic hydrocarbon solvent through an environmentally friendly processing route.

    Improving the design of catalytic materials for clean energy production requires a better understanding of their electronic properties, which remains experimentally challenging. Researchers now quantify the number of electrons transferred from metal nanoparticles to an oxide support as a function of particle size.

    Micrometre-sized silicon particles are attractive negative-electrode materials for lithium-ion batteries but are prone to mechanical failure during electrochemical cycling. Now, graphene cages grown conformally around the micro-silicon particles are shown to improve their cycling stability.

    Combined water and power models are important to predict how changes in one resource will impact the other. A new global assessment of hydropower and thermoelectric power plants predicts future vulnerabilities arising from climate-change-induced water constraints and tests possible adaptation options.

    Ontario, Canada, has seen a number of policy measures introduced since 2009 to increase wind energy production. This Perspective explores the impacts and implications of those policies on wind energy disputes in terms of health, financial benefit, community engagement and the landscape.
