Researchers use climate models to analyze past solar energy changes and test regional climate predictions under global warming scenarios. The study reveals smaller background trends in solar energy are in better agreement with long-term climate records, providing insights into Earth's changing climate.
Researchers at Princeton University have developed a new method for forming organic photovoltaic films, increasing efficiency by 50 percent. The new material is ultra-thin, flexible, and can be manufactured through printing or spraying, making it suitable for large surfaces.
Researchers recommend massive investment in alternative energy sources, including solar and wind power, to meet growing world demand. The study highlights the need for political will, targeted research and development, and international cooperation to mitigate climate change.
Researchers have developed nanoparticles that can absorb all visible light but reject invisible light, increasing the efficiency of solar cells. This technology has the potential to make solar energy dirt cheap to produce and competitive with fossil fuels.
Scientists at NASA's Goddard Space Flight Center presented new findings on lower dust absorption of sunlight, Arctic stratospheric temperature control and the impact of a large solar proton event on the atmosphere. The studies aim to improve climate modeling and understanding of climate change.
The NTUA is installing 200 photovoltaic systems at private residences in remote areas, serving a single home each. The systems provide clean and quiet power for households with limited or no electricity, improving living standards.
Researchers have directly observed magnetic field line shrinkage or reconnection outflow during solar flares, resolving a long-standing mystery. The discovery sheds light on the behavior of magnetic fields in solar flares and their impact on space weather.
Scientists have discovered a new mechanism for coronal mass ejections, which are large-scale eruptions on the Sun that can cause geomagnetic storms and disrupt power generation. Shock waves generated by solar flares in other regions of the sun can cause these eruptions, contrary to previous thought.
Czanderna's work focuses on improving photovoltaic efficiency and lifespan, with a goal of making solar energy comparable to fossil fuels. His research led to the development of an insulating material that promises to last at least six times longer.
Researchers have discovered a way to harness nature's own tool, photosynthesis, to produce hydrogen gas from sunlight and water, offering a promising alternative fuel source.
A new theory suggests that solar eruptions originate below the Sun's visible surface, rather than in its outer atmosphere. The proposed 'solar flux rope' model could improve forecasting and preparation for electrical disruptions on Earth.
The Williams College research team observed a two-and-a-half-minute period of totality in a clear sky, collecting fabulous scientific data that will keep researchers busy for years. The experiments focused on understanding the corona's temperature and magnetic field, which can reach temperatures of up to four million degrees Celsius.
The Ninth Sede Boker Symposium on Solar Electricity Production will focus on ground-breaking work in solar power generation from around the world. Experts will share knowledge and problem-solving techniques with Arab and Israeli users of a large photovoltaic system designed for agricultural communities.
Researchers at Idaho National Laboratory are exploring quantum-based phenomena to enhance computer microchips and other electronic devices. They aim to develop tiny, efficient semiconductors using quantum dots, which could lead to quantum computing and improved light-emitting applications.
Decentralized energy technologies, such as solar and wind power, are being implemented in developing countries to address electricity shortages. The symposium aims to discuss recent developments and barriers to the wider adoption of renewable energy sources.
Scientists plan to use stereo imaging to analyze the three-dimensional structures of the Sun's corona, which can help predict explosive events like coronal mass ejections and solar flares.
A solar flare on July 9, 1996, generated a massive seismic wave that resembles those created by terrestrial earthquakes. The seismic wave contained about 40,000 times the energy released in the San Francisco earthquake of 1906.
Researchers at Arizona State University have created a cell-like machine that captures light energy and converts it into a usable form, duplicating biological photosynthesis. This breakthrough technology has the potential to power artificial biological systems and could lead to innovations in computing, drug development, and other fields.
Scientists Harry van Loon and Karin Labitzke found a mirror image of the solar-stratosphere correlation in the Southern Hemisphere, spanning three solar cycles. The analysis suggests that the sun's 11-year solar cycle drives periodic changes in temperatures and pressure heights of the lower stratosphere from pole to pole.
A University of Colorado at Boulder research team found that Earth is alternately peppered by extremely high-energy electrons from the sun and Jupiter. These 'killer electrons' are accelerated to energies thousands of times higher than usual near Earth, posing a threat to spacecraft and satellites.
Researchers at Georgia Tech are using the university's rooftop solar system to study the performance and reliability of solar power systems. The system has operated close to expectations, producing 162.2 megawatt hours of electricity in its first seven-month period, but factors such as weather conditions have affected energy output.
