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

open access: yesAdvanced 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 ...

Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...
