How to design organic solar cell materials

Scientists have recently scrutinized organic solar cells and derived design rules for light-absorbing dyes that can help to make these cells more efficient, while tailoring the absorption spectrum of the cells to the needs of the chosen application.

Promising strategies for durable perovskite solar cells

(American Institute of Physics) Perovskite materials are increasingly popular as the active layer in solar cells, but internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic instability. Researchers at Soochow University examined the mechanisms at play, as well as several degradation factors that influence the performance of perovskite photovoltaics. In APL Materials, they clarified the factors influencing the degradation and they summarized some feasible approaches for durable perovskite photovoltaics.

Healthcare as a climate solution

Although the link may not be obvious, healthcare and climate change — two issues that pose major challenges around the world — are in fact more connected than society may realize. So say researchers, who are increasingly proving this to be true.

The uncertain future of the oceans

(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) Marine food webs and biogeochemical cycles react very sensitively to the increase in carbon dioxide (CO2) – but the effects are far more complex than previously thought. This is shown in a study published by a team of researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel in the journal Nature Climate Change. Data were combined from five large-scale field experiments, which investigated how the carbon cycle within plankton communities reacts to the increase of CO2.

Cicada-inspired waterproof surfaces closer to reality

A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria from establishing on the surface. The new technique – which uses commercial nail polish – is economical and straightforward, and the researchers said it will help fabricate future high-tech waterproof materials.

A new material for separating CO2 from industrial waste gases, natural gas, or biogas

With a new material, the greenhouse gas carbon dioxide (CO2) can be specifically separated from industrial waste gases, natural gas, or biogas, and thereby made available for recycling. The separation process is both energy efficient and cost-effective.

Microbial diversity below seafloor is as rich as on Earth’s surface

For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth’s largest global biomes. The research team discovered that microbial diversity in the dark, energy-limited world beneath the seafloor is as diverse as in Earth’s surface biomes.
