Unveiling the Impact of C60–O2 Interaction on the Performance and Characterization of Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.

Moving From Micro‐ to Nanofibers Within Melt Electrospinning

open access: yesJournal of Applied Polymer Science, EarlyView.
Controlling flow rate enables production of more nanofibers. This can be achieved even when electrospinning from viscous melts in a simple two‐plate geometry. Finding the optimal melt thickness to reduce flow without lowering the number of fiber‐forming jets is key.

Ferroelectric Control of Anisotropic Magnetoresistance in Ultrathin Sr2IrO4 Films toward 2D Metallic Limit

open access: yesAdvanced Physics Research, EarlyView.
Interfacing ferroelectric PbZr0.2Ti0.8O3 with ultrathin Sr2IrO4 tunes the antiferromagnetic Mott insulator into a 2D correlated metal. Switching the ferroelectric polarization induces nonvolatile, reversible resistance modulation in Sr2IrO4. The magnetoresisance in the heterostructure reveals the intriguing interplay of interfacial lattice coupling ...
