Degradation in a vacuum
Understanding the factors that reduce the power output of perovskite solar cells over time is key to their development. This image illustrates the greater structural and morphological degradation of the perovskite layer when solar cells are operated under vacuum instead of nitrogen, as observed by Renjun Guo and colleagues.

From science to policy
As the 26th UN Climate Change Conference of the Parties (COP26) in Glasgow nears, calls for politicians to heed the warnings on climate change increase. We talked to Atte Harjanne, a member of parliament in Finland, to hear how some politicians are trying to incorporate scientific findings in their decisions.

Getting closer
Understanding support for or opposition to energy developments — and how it varies with proximity — is important for effective planning. A new study using public comments on a regulatory review casts further light on the geography of discourse and how it might shape action on siting energy technology.

Infrastructure killed the electric car
When prices are adjusted for quality, electric vehicles stood their ground to petrol cars in the early twentieth century United States. If the electricity grid had developed twenty years earlier, they might have reached a 68–79% market share and CO2 emissions per car could have declined by 60%, a new study finds.

Moving beyond 99.9% Coulombic efficiency for lithium anodes in liquid electrolytes
Irreversibility is one of the biggest obstacles in realizing practical Li-metal batteries. This Review surveys the trends in Coulombic efficiency (CE)—a reversibility indicator—reported for Li-metal batteries over the last five decades, abstracts key CE descriptors and analyses promising strategies to improve CE.
