Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

open access: yesAdvanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion
