Ultra-thin transparent silver films for solar cells
12 Nov 2018 at 10:16am
A new fabrication process for transparent ultra-thin silver films has been developed. The material may help build highly efficient solar cells and light-emitting diodes. However, traditional chemical methods have not been able to produce ultra-thin and pure silver films.
New records in perovskite-silicon tandem solar cells through improved light m...
12 Nov 2018 at 10:16am
Using microstructured layers, a team has been able to increase the efficiency of perovskite-silicon tandem solar cells, achieving 25.5 %, which is the highest published value to date. At the same time, computational simulations were utilized to investigate light conversion in various device designs with different nanostructured surfaces. This enabled optimization of light management and detailed energy yield analyses.
Solar power: largest study to date discovers 25 percent power loss across UK

Regional 'hot spots' account for the power slump and these are more prevalent in the North of England than in the south.
Harvesting renewable energy from the sun and outer space at the same time
8 Nov 2018 at 11:24am
Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.
Images of photosynthetic protein complex splitting water
7 Nov 2018 at 10:38am
In a new article presents high-resolution images of photosystem II, the protein complex that splits water into hydrogen ions and oxygen during photosynthesis. The images will help researchers better understand this complex mechanism, possibly opening up the door to developing cheap and efficient solar fuel devices.
Magnetic pumping pushes plasma particles to high energies
5 Nov 2018 at 7:54am
The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.
New material cleans and splits water
5 Nov 2018 at 5:17am
Researchers have developed a photocatalytic system based on a material in the class of metal-organic frameworks. The system can be used to degrade pollutants present in water while simultaneously producing hydrogen that can be captured and used further.
Monitoring air pollution after Hurricane Maria
31 Oct 2018 at 9:48am
When Hurricane Maria struck Puerto Rico on Sept. 20, 2017, the storm devastated the island's electrical grid, leaving many people without power for months. This lack of electricity, as well as other storm-related damage, prevented air-quality monitoring in many areas. Now researchers have shown that low-cost sensors that run on solar energy can be used to monitor air pollution after a disaster.
Eye-tracking glasses provide a new vision for the future of augmented reality
29 Oct 2018 at 1:55pm
Battery-free eye-tracking glasses creates an even more realistic experience for augmented reality enthusiasts, improving player controls for gaming and allowing for more realistic image displays.
A solar cell that does double duty for renewable energy
29 Oct 2018 at 10:10am
Researchers have developed an artificial photosynthesis device called a ''hybrid photoelectrochemical and voltaic (HPEV) cell'' that turns sunlight and water into two types of energy - hydrogen fuel and electricity.
Breakthrough in process to produce hydrogen fuel
29 Oct 2018 at 7:28am
Researchers have cracked the chemical mechanism that will enable development of a new and more efficient photo-chemical process to produce hydrogen fuel from water, according to a new article.
New composite material that can cool itself down under extreme temperatures
26 Oct 2018 at 10:30am
A cutting-edge material, inspired by nature, that can regulate its own temperature and could equally be used to treat burns and help space capsules withstand atmospheric forces is under development.
Highly efficient wet-processed solar cells with molecules in the same orienta...
26 Oct 2018 at 7:26am
Researchers document a new method for controlling the orientation of conducting molecules in organic solar cells that results in the enhanced light adsorption and performance of the cells.
A first 'snapshot' of the complete spectrum of neutrinos emitted by the sun
24 Oct 2018 at 10:14am
About 99 percent of the sun's energy emitted as neutrinos is produced through nuclear reaction sequences initiated by proton-proton (pp) fusion in which hydrogen is converted into helium, say scientists.
New material, manufacturing process use sun's heat for cheaper renewable elec...
18 Oct 2018 at 9:51am
Scientists have developed a new material and manufacturing process that would make one way to use solar power -- as heat energy -- more efficient in generating electricity.
