Sunlight to solve the world's clean water crisis
16 Apr 2021 at 9:01am
Researchers have developed technology that could eliminate water stress for millions of people, including those living in many of the planet's most vulnerable and disadvantaged communities.
Transparent nanolayers for more solar power
15 Apr 2021 at 8:41am
There is no cheaper way to generate electricity today than with the sun. Solar cells available on the market based on crystalline silicon make this possible with efficiencies of up to 23 percent. With even higher efficiencies of more than 26 percent, costs could fall further. An international working group led by photovoltaics researchers now plan to reach this goal with a nanostructured, transparent material for the front of solar cells.
Solar and wind power could mitigate conflict in northeast Africa
8 Apr 2021 at 10:14am
A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa's largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region.
Carbon dots from human hair boost solar cells
8 Apr 2021 at 8:24am
Researchers have used carbon dots, created from human hair waste sourced from a barbershop, to create a kind of 'armor' to improve the performance of cutting-edge solar technology.
Framework could support more reliable electric power distribution systems
7 Apr 2021 at 10:58am
Imagine that the process of distributing electricity to homes from the power grid is like travelers boarding a train. There are multiple steps to take before they can reach their final destination.
New batteries give jolt to renewables, energy storage
5 Apr 2021 at 11:34am
Researchers have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. Now, they have shown that a new technique incorporating aluminum results in rechargeable batteries that offer up to 10,000 error-free cycles.
Polarized photovoltaic properties emerge
1 Apr 2021 at 12:13pm
For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged. The resulting effect is different from, and potentially superior to, the photovoltaic effect commonly found in solar cells.
An industrially viable competitor to silicon-based solar cells is in the works
29 Mar 2021 at 9:25am
Researchers developed a perovskite solar cell that optimized light incoupling, light trapping, and other essential properties for maximum energy conversion efficiency. With further development, the design may exceed commercial silicon-based solar cells' performance.
A general approach to high-efficiency perovskite solar cells
26 Mar 2021 at 7:47am
Researchers developed a general methodology for the reproducible fabrication of high efficiency perovskite solar cells.
Researchers harvest energy from radio waves to power wearable devices
25 Mar 2021 at 4:02pm
From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves. An international team of researchers has developed a way to harvest energy from radio waves to power wearable devices.
Floating solar farms could help reduce impacts of climate change on lakes and...
24 Mar 2021 at 8:34am
Floating solar farms could help to protect lakes and reservoirs from some of the harms of climate change, a new study suggests. However, given the complex nature of water bodies and differing designs of solar technologies, there could also be detrimental ecosystem impacts of deploying floating solar arrays.
New porous material promising for making renewable energy from water
22 Mar 2021 at 8:29am
One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for hydrogen gas production.
A new dye shakes up solar cells
19 Mar 2021 at 9:55am
Scientists have developed a new dye for solar cells that enables high power-conversion efficiency while being simple and cheap to make. The dye also works exceptionally well under low-light conditions, which is key for self- and low-powered devices.
New perovskite fabrication method for solar cells paves way to large-scale pr...
18 Mar 2021 at 11:25am
A new, simpler solution process for fabricating stable perovskite solar cells overcomes the key bottleneck to large-scale production and commercialization of this promising renewable-energy technology, which has remained tantalizingly out of reach for more than a decade.
New analysis shows potential for 'solar canals' in California
18 Mar 2021 at 9:25am
Researchers published a new study that suggests covering California's 6,350 km network of public water delivery canals with solar panels could be an economically feasible means of advancing both renewable energy and water conservation.
