New design strategies to improve the stability and efficiency of bifacial perovskite solar cells

Solar cells based on perovskites, calcium titanium oxide minerals or compounds with similar structures, are among the most promising emerging energy solutions. Over the past few years, engineers and material scientists have been exploring the potential of solar mini-modules (i.e., small cells that can be used to create larger-scale solar panels) made of perovskite bifacial structures.

The struggle to design green buildings amid shifting legal, tech landscape

The push to prepare American cities and towns for greater climate resilience has become more urgent in recent years as scientific evidence of warming mounts and extreme weather events grow more common. Officials in many states, including Massachusetts and New York, are enacting new rules requiring developers and property owners to change or reduce the type or amount of energy used in their buildings, to incorporate certain construction materials and technology while excluding others, and to plan for rising seas and stormwater runoff.

Rooftop solar panels could power one third of US manufacturing sector, claims study

Mounted on the rooftops of industrial buildings, solar panels could meet the entire electricity demand of up to 35% of U.S. manufacturers. A new study, published in Environmental Research: Infrastructure and Sustainability, investigates the feasibility of meeting these electricity demands through on-site solar panel installations for different regions and manufacturing sectors across the United States.

Creating effective assessment tools for energy-efficient buildings

Buildings are Europe’s largest energy consumer. They are responsible for about 40% of the energy consumed and 36 % of greenhouse gases emitted in the EU. However, a mere 1% undergo energy renovations each year. To meet Europe’s climate targets, buildings need to become much more energy efficient, and tools used to make this possible need to be improved.

Braided core structure boosts energy density in fiber lithium-ion batteries

An ultrathin braided wire in the core of an electrode increases the energy density of lithium-ion batteries, a team of researchers reports in the journal Angewandte Chemie International Edition. Batteries of this kind could be incorporated into functional textiles and used to supply power to smartphones and other electronic devices while we are wearing them. The new braided current collector structure replaces a single continuous wire and improves ion transport within the electrode, increasing charge density.
