Ultrawide-bandgap perovskites suffer from heterogeneities during crystallization. Zhang et al. use solvent and additive engineering to smooth the process for 2.0-eV bandgap perovskites, enabling 30.1% efficiency in all-perovskite triple-junction solar cells.

A molten-salt-mediated quenching strategy is reported for composition-invariant tuning of lattice strain in transition-metal sulfides. RuS₂ catalysts with tunable tensile strain are synthesized to investigate the strain and HER activity relationship.
