A study published in Joule demonstrates a fast, solvent-free process that boosts efficiency and operational stability of perovskite solar cells—compatible with industrial-scale manufacturing

Near-infrared fluorescent dyes hold promise for applications like bioimaging, solar energy, and more, but their synthesis is often complex. Researchers at Shibaura Institute of Technology have developed redox-switchable pyrazinacene-based dyes using an intramolecular charge transfer design. This approach enables tunable fluorescence from the visible to near/short-wave-infrared regions and supports applications such as real-time redox sensing in cells. This is useful for monitoring cellular redox processes and imbalances.
