    The appropriate descriptors for a catalyst’s hydrogen evolution activity in alkaline electrolyte are debated. Combining simulations and single-crystal studies of metal-decorated Pt surfaces, McCrum and Koper show that activity exhibits a volcano-type relationship with the hydroxide binding strength of the catalyst, providing a target for catalyst design.

    Estimating the costs of green home improvements is not possible without accurate estimates of their impact on house prices. Now, Shen et al. use the sales data of more than 400,000 properties in the United States to determine how heat pump installations increase house prices.

    Low-bandgap tin–lead perovskites are key to all-perovskite tandem solar cells but simultaneous improvement in efficiency and stability has proven challenging. Now, Li et al. fabricate tin–lead perovskite cells with reduced methylammonium content that are 20.4% efficient and stable under illumination for 450 h.

    Ensuring both stability and efficiency in mixed lead–tin perovskite solar cells is crucial to the development of all-perovskite tandems. Xiao et al. use an antioxidant zwitterionic molecule to suppress tin oxidation thus enabling large-area tandem cells with 24.2% efficiency and operational stability over 500 hours.

    The design of research solar cells is typically optimized for laboratory conditions but in the real world they are exposed to changing temperatures influencing their performance. Now, research from outdoor tests reveals how temperature alters the current of perovskite/silicon tandem solar cells and how this changes the optimal bandgaps.

    Current collectors are essential components in lithium-ion batteries, but are typically made of metal foils that do not contribute to the battery capacity. Now, a fire-extinguishing lightweight polymer-based current collector is developed that enhances both the energy density and safety of the battery.

    Government programmes such as the Advanced Research Projects Agency-Energy (ARPA-E) are designed to help cleantech companies overcome startup challenges and bring innovations to market. New analysis shows that support from ARPA-E has led to higher patenting rates but success in winning follow-up funding remains unclear.

Social Dynamics of Energy Behaviour

Energy use occurs in homes, workplaces and communities in which complex webs of social relations already exist, and social interactions routinely occur.
