Key Highlights
•
Researchers have developed a new, non-destructive interconnection layer for perovskite tandem solar cells that uses an alcohol-based material instead of a water-based one. This prevents moisture damage, leading to solar cells that are both more efficient and much more stable over time.

A new catalyst design for lithium-sulfur batteries uses single iron atoms precisely anchored to a molybdenum sulfide surface, creating a unique atomic structure that speeds up the battery’s chemical reactions. This breakthrough enables a high-performance pouch cell with an energy density of 302 Wh/kg, a significant step towards practical, high-energy batteries for electric vehicles and grid storage.

A new analysis argues that the performance of common metal-oxide cathodes in lithium and sodium-ion batteries is governed by fundamental chemical properties like bonding and structure, not just trial-and-error engineering. This perspective provides a clearer roadmap for designing next-generation cathodes that are more stable and can store more energy.
