Excitation‐Dependent Quadruple‐Level Emission from an Isolated Molecule for Dynamic Information Encryption

Advanced Science, EarlyView.
By manipulating the quadruple decoupled radiative transitions of donor and acceptor units, dual‐phase excitation‐dependent afterglow emission is achieved for the first time in a single isolated molecule. The decoupled donor‐acceptor units precisely manipulate the electron transfer pathways in ACRSP, endowing it with intrinsic single‐molecule Ex‐De ...

On the Accessibility of Higher‐n Phases in Formamidinium‐Based Ruddlesden‐Popper and Dion–Jacobson Layered Hybrid Perovskites

Advanced Electronic Materials, EarlyView.
We investigate FA‐based layered hybrid perovskites containing aromatic cations for Ruddlesden‐Popper and Dion‐Jacobson phases and explore the effect of Cs+ on the formation of n > 1 phases through a combination of techniques. We exclude the formation of higher (n > 2) phases, even in the presence of Cs+, despite improved photovoltaics, offering a ...

Unveiling the Impact of C60–O2 Interaction on the Performance and Characterization of Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.
