Electrochemical Doping for Absorption and Conductivity Tuning of P(NDI2OD‐T2) Films

Advanced Electronic Materials, EarlyView.
Electrochemical doping of P(NDI2OD‐T2) films allows for tuning the degree of doping both in liquid electrolytes as well as in the solid state. The nature of the doped species is elucidated by UV–vis spectroscopy and accompanying DFT calculations. Correlations between maximum conductivities and the presence of mixed valence states, (specifically neutral/

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

Advanced 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.
