Solution-processed organic solar modules with 10% power conversion efficiency

A new formulation for manufacturing organic solar panels exhibits an impressive, certified power conversion efficiency to help bring this technology closer to commercialization. Organic solar cells are a promising alternative to conventional PV solar panels, offering lighter-weight materials, flexibility, transparency, and low-cost manufacturing. They use organic molecules such as conductive polymers or small molecules to […]

Reducing traps increases performance of organic photodetectors

Flexible organic photodetectors (OPDs) have a huge potential for applications in low-cost imaging, health monitoring and near infrared sensing. Credit: Christian Körner Physicists at the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) discovered that trap states rule the performance of organic photodetectors, ultimately limiting their detectivity. These highly promising results have now […]

Determining Dissolved Organic Carbon Flows into the Gulf of Alaska

Amid ongoing climate change, understanding how and where carbon is moving across ecosystems has become a top research priority. This type of “carbon accounting” helps scientists determine where the planet is sequestering and releasing atmosphere-warming carbon compounds and is especially important at the boundaries between different ecosystems. In a new study, Edwards et […]

Organic meats found to have approximately the same greenhouse impact as regular meats

Credit: Pixabay/CC0 Public Domain A trio of researchers from the Technical University of Munich, the University of Greifswald and the University of Augsburg have found that the meat production process for organic meats produces approximately the same amounts of greenhouse gases as does the conventional meat production process. In their paper published in the journal […]

The research, published in Nature Communications and supported by the Welsh Government […]

Increasing the efficiency of organic solar cells — ScienceDaily

Organic solar cells are cheaper to produce and more flexible than their counterparts made of crystalline silicon, but do not offer the same level of efficiency or stability. A group of researchers led by Prof. Christoph Brabec, Director of the Institute of Materials for Electronics and Energy Technology (i-MEET) at the Chair of Materials Science […]

Pristine 'fireball’ meteorite contains extraterrestrial organic compounds

The meteorite was recovered from a frozen lake in Hamburg, Michigan in January 2018. (Brannon Naito/) Meteorites are little bundles of scientific evidence, holding secrets to deep space and how life was seeded on Earth. The problem is, it’s rare that they’re actually recovered before they are contaminated by liquid water and terrestrial microbes, rendering […]
