| Thin-film photovoltaic technology combines efficiency and versatility Posted: 27 Jun 2022 07:02 AM PDT Stacking solar cells increases their efficiency. Researchers have now produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent -- the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, portable equipment, and devices that can be folded or rolled up. |
| Insight into past--and future--of Western US wildfires Posted: 26 Jun 2022 05:02 PM PDT A new study examines the context surrounding the fires and offers insight into the historical role of large, high-severity fires -- and the future of wildfires -- west of the Cascades. |
| Climate damage caused by growing space tourism needs urgent mitigation Posted: 26 Jun 2022 05:02 PM PDT A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study. |
| Biodiversity risks to persist well beyond future global temperature peak Posted: 26 Jun 2022 05:02 PM PDT Even if global temperatures begin to decline after peaking this century because of climate change, the risks to biodiversity could persist for decades after. |
| Built infrastructure, hunting and climate change linked to huge migratory bird declines Posted: 24 Jun 2022 05:15 PM PDT New research shows how migratory birds are declining globally because of the way that humans have modified the landscape in recent decades. A total of 103 species of migrating birds were studied, including rapidly declining species like the turtle dove and the common cuckoo, using large-scale datasets. Advances in satellite imagery allowed the team to map threats across Europe, Africa and Western Asia. |
