Mobile iodides capture for highly photolysis- and reverse-bias-stable perovskite solar cells
Nature Materials, Published online: 29 April 2024; doi:10.1038/s41563-024-01876-2
Iodide-related defects pose serious challenges to the irradiation, thermal, light or reverse-bias stabilities of perovskite solar cells. Here, the authors find that by using the iodide/polyiodide capture and confine effects of perfluorodecyl iodide interfacing with perovskites, inverted perovskite solar cells achieve much improved stabilities.

Synergistic work hardening by rapid multiplication of dislocations in a multi-principal-element alloy
Nature Materials, Published online: 26 April 2024; doi:10.1038/s41563-024-01891-3
In a multi-principal-element VCoNi alloy, premature necking during Lüders banding has been harnessed to produce rapid dislocation multiplication, leading to both forest hardening and hardening induced by regions of local chemical order. The result is ductility of 20% and a yield strength of 2 GPa, during room-temperature and cryogenic deformation.

Evolution of the flat band and the role of lattice relaxations in twisted bilayer graphene
Nature Materials, Published online: 24 April 2024; doi:10.1038/s41563-024-01858-4
By combining nano-spot angle-resolved photoemission spectroscopy and atomic force microscopy, the authors resolve the fine electronic structure of the flat band and remote bands of twisted bilayer graphene as the twist angle varies, revealing a spectral weight transfer between remote bands that is attributed to lattice relaxations.

Understanding asymmetric switching times in accumulation mode organic electrochemical transistors
Nature Materials, Published online: 17 April 2024; doi:10.1038/s41563-024-01875-3
The turn-off time is generally faster than the turn-on time in accumulation mode organic electrochemical transistors (OECTs), but the mechanism is less understood. Here the authors find different transient behaviours of turn-on and turn-off in accumulation mode OECTs, and ion transport is the limiting factor of device kinetics.

Drift-free iontronic sensing enabled by a creep-free polyelectrolyte elastomer
Nature Materials, Published online: 10 April 2024; doi:10.1038/s41563-024-01851-x
Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure.
