Quantifying Optical Disorder in CsFaPb(Br,I)3 Perovskites via Urbach Energy Analysis Using OPAL2 Fresnel‐Based Simulations

Advanced Physics Research, EarlyView.
ABSTRACT This study examines light‐matter interactions in CsFAPb(Br, I)3 perovskite thin films by analyzing their absorption, reflection, and emission properties using Fresnel‐based OPAL2 simulations. The optical spectra show sharp absorption edges at 1.55 – 1.60 eV for CH3NH3PbI3 and triple‐cation perovskites, which blue‐shift to ∼1.8 eV with ...

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

Bulletin 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

Bulletin 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

Bulletin 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).
