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

Unique Na5−xSbSe Phase Enables High‐Rate Performance of Sb2Se3 Anodes in Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
The (de)sodiation mechanism of Sb2Se3 is revealed through advanced operando techniques and ab initio simulations and underscores the value of complementary methods in exploring battery mechanisms. A new Na5−xSbSe phase is identified as the final sodiation product of Sb2Se3 anodes in Na‐ion batteries (NIBs), which enables the remarkably high‐rate ...

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.

Beyond subsistence? The role of rural cooperatives in driving smallholder commercialization in Ethiopia

Agribusiness, EarlyView.
Abstract The transition from subsistence to market‐oriented agriculture holds the potential to boost rural economic progress and improve the well‐being of the rural poor in developing countries. Despite this potential, there is limited understanding of the key drivers for smallholder commercialization. In this study, we utilize comprehensive three‐wave
