Sun-soaking device turns water into superheated steam
11 Dec 2018 at 4:21pm
Engineers have built a device that soaks up enough heat from the sun to boil water and produce 'superheated' steam hotter than 100 degrees Celsius, without any expensive optics.
Perovskite solar cells: cheaper production and high efficiency
11 Dec 2018 at 8:30am
A team of chemists and physicists is offering a novel approach for the selective layer formation in perovskite solar cells. The molecule assembles itself into a monolayer, which can cover a variety of surfaces and can function as a hole transporting material in a perovskite solar cell.
Fighting smog supports solar power
6 Dec 2018 at 8:59am
Model calculations by researchers show that if China fought smog more aggressively, it could massively increase solar power production.
'Sun in a box' would store renewable energy for the grid
5 Dec 2018 at 2:19pm
Engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a small city not just when the sun is up or the wind is high, but around the clock.
Fine-tuning renewables could help Texas balance energy resources
5 Dec 2018 at 11:27am
A new study analyzes Texas' mix of wind and solar energy resources, and how to achieve better balance between them going forward.
Colloidal quantum dots make LEDs shine bright in the infrared
3 Dec 2018 at 8:16am
A group of researchers report on the development of a colloidal quantum-dot light emitting diode with unprecedented quantum and power conversion efficiencies in the infrared range. The study has proven that these devices can also be integrated in inorganic solar cells and may lead to even higher efficiencies.
New material, black silver, discovered
3 Dec 2018 at 7:14am
Researchers have discovered a new material that could lead to highly sensitive biomolecule detectors and more efficient solar cells.
Brilliant iron molecule could provide cheaper solar energy
30 Nov 2018 at 8:16am
For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.
Device could provide refrigeration for off-grid locations
28 Nov 2018 at 11:17am
A new system can provide passive cooling without the need for power, and could be used to preserve food or vaccines in hot, off-grid locations.
Explaining the plummeting cost of solar power
20 Nov 2018 at 4:38am
The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop? A new analysis has pinpointed what caused the savings, including the policies and technology changes that mattered most.
Stretchy solar cells a step closer
13 Nov 2018 at 8:54am
Scientists have developed flexible organic photovoltaics with a chemical additive that mitigates the material's brittle qualities. At the right concentration, thiol-ene molecules infiltrate the polymer material and form a mesh that makes the entire material stretchable without losing efficiency.
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
9 Nov 2018 at 7:14am
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.
