Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen

open access: yesPhysik in unserer Zeit, EarlyView.
Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.

Implementing potential climate‐smart practices through diverse partnerships

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Soil properties and road proximity likely influence plant and bacterial traits and diversity more than habitat size in small urban greenspaces

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global decline in biodiversity can be partly ameliorated by sympathetic design of green spaces within urban environments. This includes roundabouts on road systems. This study utilised a combination of approaches to assess levels of plant and bacterial diversity in roundabouts of varying size, soil characteristics and habitat complexity.
