Mesoporous MoS₂ strategy boosts efficiency and stability of perovskite solar cells

Synthesis and characterization of mesoporous MoS2. Credit: Nature Nanotechnology (2024). DOI: 10.1038/s41565-024-01799-8. The efficiency and performance of photovoltaics (PVs) have improved significantly over the past decades, which has led to an increase in the adoption of solar technologies. To further enhance the performance of solar cells, energy researchers worldwide have been devising and testing alternative […]

Sinister Solar System – NASA Science

07 NASA X-ray Telescopes Reveal the “Bones” of a Ghostly Cosmic Hand In 1895, Wilhelm Röntgen discovered X-rays and used them to image the bones in his wife’s hand, kicking off a revolutionary diagnostic tool for medicine. Now two of NASA’s X-ray space telescopes have combined their imaging powers to unveil the magnetic field “bones” […]

NASA Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft

NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown above is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This […]

This backpack solar generator can help you ignore nature

Bluetti has taken portable power to absurd levels with its new Handsfree Backpack Power Stations. They’re available in big or bigger versions depending on how long — and how much gear — you want to keep powered in the great outdoors. They’re primarily aimed at outdoor photographers, but Bluetti also thinks they’ll appeal to hikers, […]

Sun reaches maximum phase in 11-year solar cycle

Images from NASA’s Solar Dynamics Observatory highlight the appearance of the sun at solar minimum (left, Dec. 2019) versus solar maximum (right, May 2024). These images are in the 171 wavelength of extreme ultraviolet light, which reveals the active regions on the sun that are more common during solar maximum. Credit: NASA/SDO In a teleconference […]

Monster X-class flare launches massive solar storm towards Earth — and could trigger auroras this weekend

The sun has unleashed an enormous X-class solar flaretemporarily triggering a radio blackout above parts of the U.S. and unleashing a hefty coronal mass ejection (CME) that will likely slam into our planet, potentially triggering vibrant aurora displays later this week. The X-class solar flare — the most powerful type the sun can produce — […]
