Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Heat, cold extremes hold untapped potential for solar and wind energy
(via sciencedaily.com) Original source Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published Revolutionizing hydrogen production: Economical and efficient solutions unveiled
(via sciencedaily.com) Original source Scientists introduce superaerophobic three-dimensional nickel nanostructured catalysts for accelerated water electrolysis.
Published Researchers name prehistoric amphibian ancestor discovered in Smithsonian collection after Kermit the Frog
(via sciencedaily.com) Original source Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. The team of researchers described the fossil as a new species of proto-amphibian, which they named Kermitops gratus in honor of the iconic Muppet, Kermit the Frog.
Published Research suggests how turbulence can be used to generate patterns
(via sciencedaily.com) Original source Physicists show how patterns can emerge from chaos in turbulent fluids.
Published Harnessing hydrogen at life's origin
(via sciencedaily.com) Original source A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.
Published Reimagining the future of solar energy
(via sciencedaily.com) Original source New research suggests that there might be other ways to generate solar energy than just trying to make individual solar cells super-efficient.
Published Perovskite solar cells: Vacuum process may offer a short track to commercialization
(via sciencedaily.com) Original source Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.
Published 'Find pearls in the soil' unveiling the magic of hydrogen production from municipal sewage
(via sciencedaily.com) Original source Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.
Published New high-performance solar cell material
(via sciencedaily.com) Original source A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.
Published Alaska dinosaur tracks reveal a lush, wet environment
(via sciencedaily.com) Original source A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.
Published Breakthrough research enables high-density hydrogen storage for future energy systems
(via sciencedaily.com) Original source A research team has reported a groundbreaking development in efficient hydrogen storage.
Published Evolving hydrogen-storage technology: Guidelines developed for the design of anti-evaporation catalysts
(via sciencedaily.com) Original source A research team has identified materials capable of catalyzing the conversion of ortho-hydrogen to para-hydrogen. These catalysts should be essential to the spread of mass-transportation/storage of liquid hydrogen.
Published Fossil named 'Attenborough's strange bird' was the first in its kind without teeth
(via sciencedaily.com) Original source A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.
Published Researchers invent new triple-junction tandem solar cells with world-record efficiency
(via sciencedaily.com) Original source Scientists have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing triple-junction perovskite/Si tandem solar cell thus far. To achieve this, the team engineered a new cyanate-integrated perovskite solar cell that is stable and energy efficient.

(via sciencedaily.com) Original source A team of researchers has revealed ways to optimize efficiency and better control degradation, by engineering the nanoscale structure of perovskite devices.
Published Researchers improve the stability of perovskite solar cells
(via sciencedaily.com) Original source Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.
