The Value of Device Characterization for the Optimization of Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Using the example of organic photovoltaics (OPV), this study examines whether and when additional measurements can be helpful in process optimization. A virtual laboratory based on real solar cells serves as a benchmark function to compare two different approaches for process optimization, namely black‐box optimization (black circle) and model‐based ...

Stringency and dissimilarity of Maximum Residue Levels affect bilateral agri‐food trade stability

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Food standards are rising in both prevalence and stringency. They protect consumers and may enhance demand stability but also pose compliance challenges to producers, with ambiguous effects on the stability of trade relationships. We analyze the impact of importers' Maximum Residue Levels (MRLs) along with bilateral MRL dissimilarity between ...

Spin‐Selective Catalysts for Oxygen‐Involved Electrocatalysis

open access: yesAdvanced 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 ...

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
