Asymmetric Acceptor Featuring Fused‐Imidazole Central Core Enabling Organic Solar Cells with 19.4% Efficiency

open access: yesAdvanced Energy Materials, EarlyView.
Asymmetric Y‐acceptor BTQT‐4F featuring innovative fused‐imidazole central linkage, is successfully developed by 2D π‐expansion strategy. The decent power conversion efficiencies (PCEs) of 18.22% and 19.40% are achieved in the PM6:BTQT‐4F binary and PM6:BTP‐eC9:BTQT‐4F ternary organic solar cells (OSCs), respectively.

Interior Morphology and Pore Structure in High Surface Area Carbon Catalyst Supports

open access: yesAdvanced Energy Materials, EarlyView.
The interior structure of high surface area carbon supports for proton exchange membrane fuel cells is a major yet poorly characterized factor influencing performance and durability. Using full‐range electron tomography, pores and pathways within the supports are visualized in 3D.

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 ...

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.
