Researchers from the University of Potsdam, together with colleagues from other universities, have shown that ion-induced field screening is a dominant factor in the operational stability of perovskite solar cells. Their findings, published in the journal Nature Energy, lay the foundation for new strategies to improve the lifetime of the next-generation solar cells.

Unfortunately, this is not the first incident to befall animals of the Negev, as government agencies and environmental groups scramble to combat the rising toll on eagles and other animals.

Tel Aviv University archaeologists claim that elephant hunting by early humans was the reason for the proximity between Paleolithic extensive stone quarries and water sources

MIT chemical engineers have devised an efficient way to convert carbon dioxide to carbon monoxide, a chemical precursor that can be used to generate useful compounds such as ethanol and other fuels.

Scientists at Israel's Weizmann Institute of Science got lucky and managed to spot a star in a nearby galaxy go supernova, able to make a portrait of the star's last days.

Black holes are extraordinarily dense objects with gravity so strong that not even light can escape, making viewing them extremely challenging.

Hebrew University experts devise a non-invasive method for chickpea irrigation evaluation, aiding sustainability and global food security.

A new fabrication process that could be used to build a quantum computer achieves an almost zero failure rate and has the potential to be scaled up, according to new research from engineers and physicists at UCL.

Semiconductors are the basic building blocks of microchips. These technological marvels are in everything from lightbulbs and toothbrushes to cars, trains and planes, not to mention the vast array of electronics that have become integral to many people's daily lives.

Flexible solar cells have many potential applications in aerospace and flexible electronics, but low energy conversion efficiency has limited their practical use. A new manufacturing method has increased the power efficiency of flexible solar cells made from perovskite, a class of compounds with a specific crystalline structure that facilitates the conversion of solar energy into electricity.

Lithium-ion batteries contain flammable materials that could pose a safety risk under certain conditions. Dr. Yaser Abu-Lebdeh is one of the researchers using the Canadian Light Source (CLS) at the University of Saskatchewan to develop a safer alternative: solid-state batteries.

New multidisciplinary research from the University of St Andrews could lead to more efficient televisions, computer screens, and lighting.

More than 20 years of research in solar radiation at the National Renewable Energy Laboratory (NREL) is now poised to advance power system planning and solar energy deployment across Africa, Eastern Europe, and the Middle East.

Google and the XPrize Foundation have launched a competition worth US$5 million (£4 million) to develop real-world applications for quantum computers that benefit society—by speeding up progress on one of the UN Sustainable Development Goals, for example. The principles of quantum physics suggest quantum computers could perform very fast calculations on particular problems, so this competition may expand the range of applications where they have an advantage over conventional computers.

A container ship struck the Francis Scott Key Bridge in Baltimore on Tuesday morning, causing it to partially collapse into the river below.

A new study has shown that people modify their behavior to accommodate autonomous delivery robots, and it is this invisible "human work" that allows robots to run smoothly on the streets and needs to be considered when designing their routes.

A Washington State University-led 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.

Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous waterborne diseases like cholera.

Researchers from the RIKEN Center for Emergent Matter Science and collaborators 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.

When FAMU-FSU College of Engineering Professor Fang Peng was a boy, he saw the power and peril of electricity firsthand. He was in middle school when his remote Chinese hometown first received electric service. His family shared a single portable, 15-watt light bulb attached to a cable. It was his job to replace the bulb.
