Published Thin, lightweight layer provides radiation barrier for perovskites in space, protection from elements on Earth
(via sciencedaily.com) An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research.
Published Stability of perovskite solar cells reaches next milestone
(via sciencedaily.com) Perovskite semiconductors promise highly efficient and low-cost solar cells. However, the semi-organic material is very sensitive to temperature differences, which can quickly lead to fatigue damage in normal outdoor use. Adding a dipolar polymer compound to the precursor perovskite solution helps to counteract this. The solar cells produced in this way achieve efficiencies of well above 24 %, which hardly drop under rapid temperature fluctuations between -60 and +80 Celsius over one hundred cycles. That corresponds to about one year of outdoor use.
Published Meteorites reveal likely origin of Earth's volatile chemicals
(via sciencedaily.com) By analyzing meteorites, researchers have uncovered the likely far-flung origin of Earth's volatile chemicals, some of which form the building blocks of life.

Published Theoretical computations identify a solid-state hydrogen storage material's key bottleneck
(via sciencedaily.com) Magnesium hydride has long been touted for its potential to store large amounts of hydrogen, something essential if hydrogen is to play a role in powering a sustainable future. Yet, sluggish dehydrogenation kinetics and the high temperature required to decompose and produce hydrogen from the material have stymied its use. Now, researchers have identified why this is so, paving the way for future design guidelines and widespread commercial use.
Published Improving perovskite solar cell resistance to degradation
(via sciencedaily.com) Despite their huge potential, the way perovskite solar cells respond to external stimuli -- such as heat or moisture -- has a considerable impact on their stability. Researchers have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.

Published New study models the transmission of foreshock waves towards Earth
(via sciencedaily.com) As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.
Published Scientists discover a novel photophysical mechanism that has achieved record-breaking efficiency for organic photovoltaics
(via sciencedaily.com) Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.
