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

Advanced 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 ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Advanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Spin‐Selective Catalysts for Oxygen‐Involved Electrocatalysis

Advanced Energy and Sustainability Research, EarlyView.
The sluggish kinetics of oxygen‐involved electrocatalysis hinders the efficiency of the energy conversion process, which can be promoted by using spin‐polarized materials to conduct spin‐selective electron transfer. This review delivers a thorough and timely overview of state‐of‐the‐art spin‐selective catalysts, aiming to offer a clear route for ...

Reusable ReOx‐Pd/CeO2 Catalyst with Low Metal Surface Concentration for Efficient Consecutive Deoxydehydration and Hydrogenation of Vicinal OH Groups

Advanced Energy and Sustainability Research, EarlyView.
Less metal, more distance! The ReOx‐Pd/CeO2 catalyst, an active heterogeneous catalyst for the consecutive deoxydehydration and hydrogenation of vicinal diol, suffers a gradual loss of activity throughout its use due to the polymerization of monomeric ReOx active species.
