Climate conditions affect solar cell performance more than expected
13 Dec 2017 at 11:37am
Researchers can now predict how much energy solar cells will produce at any location worldwide. Surprisingly, they identified that two types of solar cells can vary in energy output by 5 percent or more in tropical regions. This gap occurs because solar energy can shift depending on local temperature and water in the atmosphere. Their work emphasizes that solar products may behave differently depending on their environment.
Glass with switchable opacity could improve solar cells and LEDs
11 Dec 2017 at 11:57am
Researchers have created glass that lets through a large amount of light while appearing hazy, a combination of properties that could help boost the performance of solar cells and LEDs.
Guanidinium stabilizes perovskite solar cells at 19 percent efficiency
8 Dec 2017 at 8:35am
Incorporating guanidinium into perovskite solar cells stabilizes their efficiency at 19 percent for 1,000 hours under full-sunlight testing conditions, report scientists.
Transformation to wind and solar achievable with low indirect GHG emissions
8 Dec 2017 at 8:35am
Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.
Solar eclipse: Using adaptive optics to understand eye damage
7 Dec 2017 at 11:17am
In a first-of-its-kind study, researchers are using adaptive optics (AO) to analyze retinal eye damage from the August solar eclipse on a cellular level. The research could help doctors develop a deeper understanding of this rare condition, called solar retinopathy, which has no currently accepted treatment.
Solar power advances possible with new 'double-glazing' device
7 Dec 2017 at 9:59am
A new 'double-glazing' solar power device -- which is unlike any existing solar panel and opens up fresh opportunities to develop more advanced photovoltaics -- has been invented.

4 Dec 2017 at 6:12am
Scientists have developed a new low-cost, environmentally friendly photon upconversion platform that achieves high thermal stability using deep eutectic solvents. Deep eutectic solvents are an emerging class of solvents that are a cost-effective and sustainable alternative to ionic liquids.
Why the future of clean energy storage lies in hydrogen
28 Nov 2017 at 8:01pm
As renewable sources of energy like wind and solar gain traction, scientists and engineers are eyeing new ways to store that energy in a cost-efficient manner ? laying the groundwork for a future in which renewables rival fossil fuels in powering our homes and vehicles.
Addition of tin boosts nanoparticle's photoluminescence
28 Nov 2017 at 8:01pm
Researchers have developed germanium nanoparticles with improved photoluminescence, making them potentially better materials for solar cells and imaging probes. The research team found that by adding tin to the nanoparticle?s germanium core, its lattice structure better matched the lattice structure of the cadmium-sulfide coating which allows the particles to absorb more light.
Switchable solar window developed
28 Nov 2017 at 9:01am
Thermochromic windows capable of converting sunlight into electricity at a high efficiency have been developed. Relying on such advanced materials as perovskites and single-walled carbon nanotubes, the new technology responds to heat by transforming from transparent to tinted. As the window darkens, it generates electricity.
Harvesting the sun for power and produce: Agrophotovoltaics increases the lan...
27 Nov 2017 at 9:48am
Until now, acreage was designated for either photovoltaics or photosynthesis, that is, to generate electricity or grow crops. An agrophotovoltaics (APV) pilot project, however, has now demonstrated that both uses are compatible. Dual use of land is resource efficient, reduces competition for land and additionally opens up a new source of income for farmers, say researchers.

A newly developed device could reduce the carbon footprint of ethylene production, report scientists.
Watching atoms move in hybrid perovskite crystals reveals clues to improving ...
21 Nov 2017 at 10:23am
The discovery of nanoscale changes deep inside hybrid perovskites could shed light on developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, a team of researchers discovered how the movement of ions in hybrid perovskites causes certain regions within the material to become better solar cells than other parts.
Artificial photosynthesis gets big boost from new catalyst
20 Nov 2017 at 8:13am
A new catalyst brings researchers one step closer to artificial photosynthesis -- a system that, just like plants, would use renewable energy to convert carbon dioxide (CO2) into stored chemical energy. By both capturing carbon emissions and storing energy from solar or wind power, the invention provides a one-two punch in the fight against climate change.
Hydrogen cars for the masses one step closer to reality, thanks to invention
20 Nov 2017 at 6:37am
A new device that can inexpensively and efficiently create and store energy and create hydrogen fuel, and that needs only sunlight to operate, has now been developed by researchers.
