Which climates are best for passive cooling technologies?
25 Jun 2019 at 10:35am
Researchers recently set out to gain a better understanding of the thermal balance of power plants and surfaces, but quickly realized that they would need to determine what roles cloud cover and relative humidity play in the transparency of the atmosphere to radiatio. The group presents detailed radiative cooling resource maps they created to help determine the best climates for large-scale deployment of passive cooling technologies.
Researchers create multi-junction solar cells from off-the-shelf components
24 Jun 2019 at 1:11pm
In a proof-of-concept paper, researchers detail a new approach for creating multi-junction solar cells using off-the-shelf components, resulting in lower cost, high-efficiency solar cells for use in multiple applications.
Researchers clear runway for tin based perovskite solar cells
24 Jun 2019 at 8:09am
Researchers believe their tin based perovskite solar cell could clear the runway for solar panel technology to take off.
Perovskite solar cells tested for real-world performance -- in the lab
20 Jun 2019 at 9:14am
Researchers bring diurnal and seasonal variations into the lab to test the performance of perovskite solar cells under realistic conditions.
Special nanotubes could improve solar power and imaging technology
19 Jun 2019 at 10:48am
Physicists discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.
'Hot spots' increase efficiency of solar desalination
18 Jun 2019 at 6:01am
Researchers showed they could boost the efficiency of their nanotechnology-enabled solar membrane desalination system by more than 50% simply by adding inexpensive plastic lenses to concentrate sunlight into 'hot spots.'
'Self-healing' polymer brings perovskite solar tech closer to market
17 Jun 2019 at 9:51am
A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), report scientists. Adding a 'self-healing' polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.
Carbon-neutral fuel made from sunlight and air
13 Jun 2019 at 7:31am
Researchers have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions.
Breathing new life into dye-sensitized solar cells
12 Jun 2019 at 3:11pm
Researchers are poised to reboot the field of aromatic-fused porphyrin sensitizers for dye-sensitized solar cells, the most efficient solar efficient solar technology available at present.
Clarifying the economic value of adjusting the power consumption
10 Jun 2019 at 8:15am
The economic value of demand response that adjusts the power consumption has not been clarified. A control method for maximizing cost-effectiveness of demand response is developed. Using this method, the optimal power consumption can be calculated based on the prediction of the power generation cost and the demand.
Precision calibration empowers largest solar telescope
3 Jun 2019 at 9:45am
As with any astronomical instrument, calibration is required in order to remove effects that the instrument itself might have on the data. New research marks a substantial advance in ensuring the accurate solar information measured and collected by the Daniel K. Inouye Solar Telescope (DKIST).
A rose inspires smart way to collect and purify water
29 May 2019 at 11:51am
A new device for collecting and purifying water was inspired by a rose and, while more engineered than enchanted, is a dramatic improvement on current methods. Each flower-like structure costs less than 2 cents and can produce more than half a gallon of water per hour per square meter.
Societal values and perceptions shape energy production and use as much as ne...

Societal values and perceptions have shaped the energy landscape as much as the technologies that drive its production and consumption, a new article suggests.
New York state winters could pose solar farm 'ramping' snag for power grid
28 May 2019 at 4:30pm
With low energy demand around midday in the winter, combined with solar-electricity production, New York's power system could face volatile swings of 'ramping' -- which is how power system operators describe quick increases or decreases in demand.
Helping cities make power grids safer, more reliable
28 May 2019 at 9:06am
Solar power researchers have traditionally used the power measurements from single residential solar photovoltaic systems to estimate the power generated within a city. But one installation isn't a good representation of all rooftops. Data from systems across a city is desperately needed to fully understand how this energy source can be integrated into the power grid. Engineers have provided a freely available quality-controlled and tuned dataset from 1,287 residential installations across Australia.
