Coal plant offsets with carbon capture means covering 89 percent of the US in forests
Researchers found that using bio-sequestration to capture carbon produced by US coal-fired plants even after carbon capture and storage would require using 62 percent of the nation's arable land for that process, or 89 percent of all US land with average forest cover. In comparison, offsetting the amount of carbon produced by manufacturing solar panels is 13 times less land, making it a far more viable option. (2018-09-07)

Researchers use silicon nanoparticles for enhancing solar cells efficiency
An international research group improved perovskite solar cells efficiency by using materials with better light absorption properties. For the first time, researchers used silicon nanoparticles. Such nanoparticles can trap light of a broad range of wavelengths near the cell active layer. The particles themselves don't absorb light and don't interact with other elements of the battery, thus maintaining its stability. The research was published in Advanced Optical Materials.

European researchers develop a new technique to forecast geomagnetic storms
Flashes of brightness known as solar flares can be followed by coronal mass ejections that send plasma from the sun into space.

Jupiter had growth disorders
Researchers of the Universities of Bern and Zürich and of ETH Zürich show how Jupiter was formed. Data collected from meteorites had indicated that the growth of the giant planet had been delayed for two million years. Now the researchers have found an explanation: Collisions with kilometer-sized blocks generated high energy, which meant that in this phase hardly any accretion of gas could take place and the planet could only grow slowly.

Researchers at the University of New Mexico uncover remnants of early solar system
Scientists believe the solar system was formed some 4.6 billion years ago when a cloud of gas and dust collapsed under gravity possibly triggered by a cataclysmic explosion from a nearby massive star or supernova.

Insight into loss processes in perovskite solar cells enables efficiency improvements
In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the Helmholtz-Zentrum Berlin (HZB) were able to reach this interesting conclusion through extremely accurate quantitative measurements on 1 cm2 perovskite cells using photoluminescence. Their results contribute to improving perovskite solar cells and have now been published in Nature Energy. (2018-08-01)
