Defect engineering for highly efficient and stable perovskite top cells for Si tandems

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Roles of 2D halide perovskites in 2D/3D heterojunctions for high‐performance perovskite solar cells

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review establishes a design framework for two‐dimensional (2D)/three‐dimensional (3D) perovskite heterojunctions, redefining the 2D perovskite layer as an active semiconductor component. We classify 2D structures by spacer chemistry and analyze their roles within the heterojunction.

Enantiomeric engineering of chiral perovskite interface for enhanced operational durability of perovskite solar cells

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Enantiomeric engineering with different enantiomeric ratios of chiral methylbenzene bromide constructs densely packed heterochiral interfaces, suppressing environmental degradation to boost solar cell efficiency to 25.79% and extend operational stability (T95 > 600 h).

Atomically precise metal cluster enzymes for pathological tissue regeneration

open access: yesBMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.
