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

open access: yesAdvanced 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

Advanced Liquid Electrolyte Design for High‐Voltage and High‐Safety Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review summarizes the key challenges in designing high‐voltage, safe electrolytes for lithium metal batteries (LMBs), including dendrite growth, interfacial instability, and flammability. The corresponding strategies cover regulating salt concentrations, designing fluorinated weakly solvating solvents, applying ionic liquids, and developing flame ...

The future of dispute resolution in international trade

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Given ongoing dysfunction of the World Trade Organization's Appellate Body, the focus of this article is on the future of trade dispute resolution, with evaluation of two questions: (i) What is the current status of WTO dispute resolution as compared to that conducted through existing preferential trade agreements (PTAs)? and (ii) What are the
