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

The Role and Impact of Rooftop Photovoltaics in the Norwegian Energy System under Different Energy Transition Pathways

Advanced Energy and Sustainability Research, EarlyView.
This study investigates the impact and cost‐competitiveness of rooftop solar power in a highly hydropower‐driven northern energy system toward 2050. The role of rooftop photovoltaics (PV) is assessed under different energy transition pathways and through a sensitivity analysis aiming to disclose important barriers to PV investments in the energy system.

Synthesis of Pt Carbon Aerogel Electrocatalysts with Multiscale Porosity Derived from Cellulose and Chitosan Biopolymer Aerogels via Supercritical Deposition for Hydrogen Evolution Reaction

Advanced Energy and Sustainability Research, EarlyView.
The synthesis of platinumcarbon aerogel electrocatalysts with multiscale porosity derived from biopolymer aerogels via supercritical deposition is presented. The electrocatalysts demonstrate similar overpotentials to commercial alternatives with significantly higher platinum loadings, while exhibiting superior stability due to enhanced porosity ...

Who is willing to pay a premium for leafy greens produced by indoor agriculture? A comparative choice experiment with US consumers

Agribusiness, EarlyView.
Abstract Indoor agriculture (IA) presents a pathway to producing leafy greens more sustainably by strictly controlling the growing environment, increasing the efficiency of water and land resources use, reducing pesticide application, and enhancing quality characteristics.

The effects of agricultural machinery services and land fragmentation on farmers' straw returning behavior

Agribusiness, EarlyView.
Abstract Straw returning is important for rural ecological management and sustainable agricultural development. Using farm survey data for Anhui Province, China, in 2020, we applied the double‐hurdle model to investigate the impact of agricultural machinery services and land fragmentation on farmers' straw‐returning behavior, and to explore the ...
