Pore Sieving and Surficial Charge‐Driven Desolvation for High Spatial Charge Density Carbon Cathodes in Zinc‐Ion Hybrid Capacitors

open access: yesAdvanced Energy Materials, EarlyView.
A dual‐regulation strategy integrating pore architecting and surface charge modulation is engineered in multi‐channeled carbon nanofibers, enabling efficient electric double layer compacting and interfacial [Zn(H2O)6]2+ desolvation for high spatial density charge storage.

Critical Role of Non‐Fullerene Crystalline Domains in Stabilizing Charge Separation in Bulk Heterojunction Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A crucial factor in stabilized charge generation in high‐performance PM6:Y6 organic solar cells is the LUMO level offset between mixed and pure Y6 domains. This offset enhances electron–hole spatial separation, reducing recombination losses. As the pure Y6 domain shrinks, increased bimolecular recombination significantly lowers the photocurrent and ...

How to Test Triboelectric Nanogenerators: Key Factors for Standardized Performance Evaluation

open access: yesAdvanced Energy Materials, EarlyView.
This paper is a guide on how to test triboelectric nanogenerators (TENGs) so that results can be reliably compared across different laboratories. It explores the many factors (fabrication, mechanical, electrical, and environmental) that can affect TENG testing results and provides recommendations for best practice in testing and performance evaluation.
