Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

open access: yesAdvanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Pyridinium Cations Act as Charge Reservoirs in Expanded Halide Perovskite Analogs at High Pressure

open access: yesAngewandte Chemie, EarlyView.
Redox‐innocent pyridinium derivatives can act as charge reservoirs in expanded tin‐iodide perovskite analogs. Material compression reduces the energy gap between the pyridinium π* acceptor orbital and the valence‐band maximum, facilitating electron transfer from the framework to the molecules and thereby significantly increasing electronic conductivity
