To develop redshifted dimeric acceptors, multi-selenophene strategies are adopted to deliver DYSe-1 and DYSe-2 for the first time. Due to their effective absorption extending to ≈920 nm and reduced energy losses, DYSe-1 and DYSe-2-based organic solar cells exhibit outstanding short-circuit current density over 27 mA cm−2, resulting in their promising...

Carbon-embedded Pt alloy cluster catalysts, including PtFe, PtCo, and PtNi, are developed to minimize Pt usage in proton exchange membrane fuel cells (PEMFCs). The Pt alloy clusters are stabilized within a carbon matrix, while still allowing gaseous oxygen transfer. Demonstrating high activity with low Pt loading, this catalyst exhibits exceptional...

Long-term outdoor monitoring data are combined with energy yield modeling to quantitatively and qualitatively investigate the effect of light-soaking metastability in both single-junction and tandem perovskite-based PV devices. Using a novel empirical formalism, the energy harvesting losses associated with the light-soaking effect are analyzed for...
