Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells
This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.

We show that many hydrogen‐related effects in silicon solar cells can be explained by direct electron‐assisted acceptor‐hydrogen pair dissociation. Most importantly, it leads to a high concentration of atomic hydrogen, which is highly reactive and diffusive. We provide a unified physical description of LeTID.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...
