Novel materials convert visible into infrared light
16 Jan 2019 at 10:08am
Scientists have succeeded in developing a chemical process to convert visible light into infrared energy, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity light exposure.
Power stations driven by light
15 Jan 2019 at 10:28am
The smallest building blocks within the power stations of organisms which get their energy directly from the sun are basically miniature reactors surrounded by collectors which capture photons and forward them to the center. The close correlation between structure and interaction of the components boosts productivity, a strategy which researchers are using for increasing the efficiency of solar technology.
A new way to measure solar panel degradation
10 Jan 2019 at 11:17am
How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.
Racial inequality in the deployment of rooftop solar energy in the United Sta...

Fewer rooftop solar photovoltaics installations exist in African-American and Hispanic-dominant neighborhoods than in white-dominant neighborhoods, even when controlling for household income and home ownership, according to a new study.
New materials could help improve the performance of perovskite solar cells
10 Jan 2019 at 11:16am
New research could lead to the design of new materials to help improve the performance of perovskite solar cells (PSCs).
Great potential for floating solar photovoltaics systems
8 Jan 2019 at 9:54am
Researchers estimate that installing floating solar photovoltaics on the more than 24,000 human-made US reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings reveal for the first time the potential for floating PV to produce electricity in the United States.
Seawater turns into freshwater through solar energy: A new low-cost technology
7 Jan 2019 at 10:12am
Engineers have developed an innovative, low-cost technology to turn seawater into drinking water, thanks to the use of solar energy alone.
Team locates nearly all US solar panels in a billion images with machine lear...
19 Dec 2018 at 8:55am
Researchers have identified the GPS locations and sizes of almost all US solar power installations from a billion images. Using the data, which is public, they identified factors that promote the use of solar energy and those that discourage it.
Assessing the promise of gallium oxide as an ultrawide bandgap semiconductor
18 Dec 2018 at 8:51am
In microelectronic devices, the bandgap is a major factor determining the electrical conductivity of the underlying materials, and a more recent class of semiconductors with ultrawide bandgaps are capable of operating at much higher temperatures and powers than conventional small-bandgap silicon-based chips. Researchers now provide a detailed perspective on the properties, capabilities, current limitations and future developments for one of the most promising UWB compounds, gallium oxide.
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.
