Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Is UK agriculture sustainable? Environmentally adjusted economic accounts for UK agriculture [PDF]

open access: yes, 2001
Agricultural sectors in most advanced economies have come under severe criticism for lacking the characteristics of 'sustainability'. What is usually meant is that a combination of subsidies and modern farming methods is producing an economically and ...

Superior Adhesion of Monolayer Amorphous Carbon to Copper

open access: yesAdvanced Materials, EarlyView.
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...

Queer Farmers: Sexuality and the Transition to Sustainable Agriculture [PDF]

open access: yes, 2016
Intimate relationships are foundational to farm viability. Such relationships affect how farmers share tasks, earn income, and access land, yet the role of sexuality and heteronormativity in agriculture remains understudied.

Halide Perovskite Photocatalysts for Clean Fuel Production and Organic Synthesis: Opportunities and Challenges

open access: yesAdvanced Materials, EarlyView.
This review provides the state‐of‐the‐art overview of halide perovskite‐based photocatalysts for hydrogen production from water and halogen acid solutions, CO2 reduction into value‐added chemicals, and organic chemical transformations. Different types of halide perovskite photocatalysts and their relative efficiencies for hydrogen generation and CO2 ...
