Making solar cells is like buttering bread
21 Mar 2019 at 10:03am
Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge. The techniques developed so far have produced rather poor results. However, scientists have now cracked it -- using a blade and a dipping solution.
True-meaning wearable displays: Self-powered, washable and wearable
21 Mar 2019 at 7:28am
When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source.
Researchers create hydrogen fuel from seawater
18 Mar 2019 at 12:17pm
Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A team has now developed a way to harness seawater -- Earth's most abundant source -- for chemical energy.
Solar-powered moisture harvester collects and cleans water from air
14 Mar 2019 at 9:31am
A breakthrough by engineers offers new solution through solar-powered technology that absorbs moisture from the air and returns it as clean, usable water. This 'super-sponge' could be used in disaster situations, poverty-stricken areas and developing countries.
Powering devices -- with a desk lamp?
13 Mar 2019 at 7:32am
Batteries power most of our devices, and even some cars. But researchers now report in ACS Applied Materials & Interfaces a step toward running electronic devices in homes and offices on the light coming from lamps scattered around the room. The team developed special light harvesters, like those used for solar power, optimized to produce energy from ambient indoor lighting.
Finding the right 'dose' for solar geoengineering
11 Mar 2019 at 9:51am
New research finds that if solar geoengineering is used to cut global temperature increases in half, there could be worldwide benefits without exacerbating change in any large geographic area.
New cell-sized micro robots might make incredible journeys
7 Mar 2019 at 1:19pm
Researchers have created tiny functional, remote-powered, walking robots, developing a multistep nanofabrication technique that turns a 4-inch specialized silicon wafer into a million microscopic robots in just weeks. Each one of a robot's four legs is just under 100-atoms-thick, but powered by laser light hitting the robots' solar panels, they propel the tiny robots. The researchers are now working on smart versions of the robots that could potentially make incredible journeys in the human body.
Spectroscopy on individual molecules
7 Mar 2019 at 10:15am
While spectroscopic measurements are normally averaged over myriad molecules, a new method provides precise information about the interaction of individual molecules with their environment. This will accelerate the identification of efficient molecules for future photovoltaic technologies, for example.
Shifting away from coal is key to cutting greenhouse gas emissions
7 Mar 2019 at 7:32am
The United States could fulfill its greenhouse gas emission pledge under the Paris Climate Agreement by virtually eliminating coal as an energy source by 2024, according to new research.
Improving solar cell efficiency with a bucket of water
6 Mar 2019 at 9:53am
Beth Parks has devised an astonishingly simple way to overcome a limitation of solar cells -- a bucket of water. She developed a frame that holds the solar cell with a bucket suspended on either end. By controlling the leak of water from one of the buckets, the solar cell shifts, tracking the arc of the sun throughout the day.
Good news! Europe's electric grid will still work even as the world crumbles
6 Mar 2019 at 8:07am
Temperatures may climb and seas may rise, but the lights (and, undoubtedly, the air conditioning) will still be on in nations with high capacities for wind and solar energy. New research suggests that these electricity systems should work almost equally well in both historical and future European climates despite changing weather patterns.
Light from an exotic crystal semiconductor could lead to better solar cells
6 Mar 2019 at 5:17am
Scientists have found a new way to control light emitted by exotic crystal semiconductors, which could lead to more efficient solar cells and other advances in electronics, according to a new study.
Machine learning used to identify high-performing solar materials
5 Mar 2019 at 6:28am
Thanks to a study that combines the power of supercomputing with data science and experimental methods, researchers have developed a novel 'design to device' approach to identify promising materials for dye-sensitized solar cells (DSSCs).
Chirality yields colossal photocurrent
4 Mar 2019 at 9:16am
Typically, light is converted to electricity by chemically altering a semiconductor to have a built-in electric field. A team of researchers has developed an alternative means using a unique semi-metal that intrinsically generates direct current through the nonlinear mixing of the waves of light.
Layering titanium oxide's different mineral forms for better solar cells
28 Feb 2019 at 6:36am
A research team has improved the efficiency of a new type of solar cell with a double layer consisting of pure anatase and brookite, two different mineral forms of titanium oxide. Using water-solute brookite nanoparticles, a brookite layer was fabricated on top of anatase, increasing solar cell efficiency by up to 16.82 percent.
