Solvated PbI2 Clusters Preceding the Crystallization of Lead Halide Perovskites–a UV/VIS In Situ Study

open access: yesAdvanced Electronic Materials, EarlyView.
This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.

Strain‐Induced Polarization Rotation in Freestanding Ferroelectric Oxide Membranes

open access: yesAdvanced Electronic Materials, EarlyView.
Combining piezoresponse force microscopy, Raman spectroscopy, and scanning transmission electron microscopy, the ferroelectric polarization of a Pb(Zr,Ti)O3 membrane is mapped in a fold‐like structure. A polarization rotation from out‐of‐plane to in‐plane is evidenced, occurring at a low strain threshold (≈0.2%), and is suggested to be entirely driven ...

Spatially Regulated Gas Flow Control for Batch‐Drying of Large Area Slot‐Die‐Coated Perovskite Thin Films

open access: yesAdvanced Energy Materials, EarlyView.
Innovations are crucial for transferring high power conversion efficiencies (PCEs) to large‐scale perovskite devices. Here, a 2D regulated gas flow control for batch‐drying of slot‐die‐coated perovskite films is introduced. This drying method achieves homogeneous, pinhole‐free large‐area perovskite/silicon tandem solar cells and perovskite solar ...
