Better silicon solar panels
19 Oct 2021 at 7:32pm
Researchers are applying a new technique to identify defects in silicon solar cells that cause a drop in efficiency. The lessons learned at the atomic level could lead to improvements in the way manufacturers strengthen their products against what is known as light-induced degradation.
New technique paves the way for perfect perovskites
19 Oct 2021 at 8:05am
Scientists have developed a new technique that allows researchers to synthesize a perovskite solar material, characterize its crystal structure, and test its response to light at the same time.
Putting honeybee hives on solar parks could boost the value of UK agriculture
18 Oct 2021 at 2:22pm
The value of UK agriculture could be boosted by millions of pounds a year if thousands of honeybee hives were deployed on solar parks across the country, a new study reveals. However, scientists caution that the benefits of managing solar parks for wild pollinators over honeybees should be prioritized where appropriate and should be assessed on a site by site basis.
Solar energy can be cheap and reliable across China by 2060
18 Oct 2021 at 1:32pm
How much will solar power really cost in China in the coming decades, including the challenges its inherent variability poses to the grid? Researchers have found that solar energy could provide 43.2% of China's electricity demands in 2060 at less than two-and-a-half U.S. cents per kilowatt-hour.
Scientists discover method to boost energy generation from microalgae
18 Oct 2021 at 7:59am
The variety of humble algae that cover the surface of ponds and seas could hold the key to boosting the efficiency of artificial photosynthesis, allowing scientists to produce more energy and lower waste in the process. A study showed how encasing algae protein in liquid droplets can dramatically enhance the algae's light-harvesting and energy-conversion properties by up to three times. This energy is produced as the algae undergoes photosynthesis, which is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. When light hits the droplet, light waves travel around the curved edges of the droplet. Light is effectively trapped within the droplet for a longer period of time, giving more opportunity for photosynthesis to take place, hence generating more energy.
Expansion of wind and solar power too slow to stop climate change
14 Oct 2021 at 11:19am
The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in the journal Nature Energy, written by Aleh Cherp, Vadim Vinichenko, Jale Tosun, Joel A.Gordon and Jessica Jewell.
Scientists develop fully solar-driven autonomous chemical mini-plant
14 Oct 2021 at 11:19am
Scientists have developed a fully operational standalone solar-powered mini-reactor which offers the potential for the production of fine chemicals in remote locations on Earth, and possibly even on Mars.
Climate change threatens hydropower energy security in the Amazon basin
14 Oct 2021 at 10:11am
Hydropower is the dominant source of energy in the Amazon region, the world's largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the Amazon's hydropower capacity.
Environmentally friendly ways to cool homes
7 Oct 2021 at 12:35pm
The summer of 2021 in Western Canada was one of the hottest on record. In the Canadian province of British Columbia alone, 59 weather stations registered their hottest temperatures ever on June 27. For those lucky enough to have air conditioners, keeping their homes cool during the heat dome was relatively easy. However, the comfort lasted only until the utility bills arrived. As a result of heatwaves around the world, global electricity demand increased by five per cent so far in 2021 and it is expected to continue to increase annually.
Large scale solar parks cool surrounding land
5 Oct 2021 at 9:48am
Researchers studying two solar parks, situated in arid locations, found they produced 'cool islands' extending around 700 meters from the solar park boundaries. The temperature of surrounding land surface was reduced by up to 2.3 degrees at 100 meters away from the solar park, with the cooling effects reducing exponentially to 700 meters. This new discovery is important as it shows the solar park could impact ecological processes, including productivity, decomposition, and ultimately the carbon balance, in the surrounding landscape.
Researchers identify and clear efficiency hurdle for organic solar cells
29 Sep 2021 at 8:28am
Researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be overcome.
New imaging system reveals solar panel defects even in bright sunlight
27 Sep 2021 at 2:29pm
Researchers describe how a unique combination of new hardware and software allows defects in solar panels to be clearly imaged and analyzed even in bright light.
Solar cells with 30-year lifetimes for power-generating windows
14 Sep 2021 at 8:12am
A new transparency-friendly solar cell design could marry high efficiencies with 30-year estimated lifetimes, new research has shown. It may pave the way for windows that also provide solar power.
Time to shine: Scientists reveal at an atomic scale how chlorine stabilizes n...
10 Sep 2021 at 9:16am
Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of solar power technology, showing how power-boosting and stability-enhancing chlorine is incorporated into the perovskite material.
Combining sunlight and wastewater nitrate to make the world?s No. 2 chemical
8 Sep 2021 at 3:05pm
Engineers have created a solar-powered electrochemical reaction that not only uses wastewater to make ammonia -- the second most-produced chemical in the world -- but also achieves a solar-to-fuel efficiency that is 10 times better than any other comparable technology.
