Solar panel demand causing spike in worldwide silver prices
17 Apr 2019 at 7:27am
Rising demand for solar panels is having a major effect on the worldwide price of silver, which could lead to solar panel production costs becoming far higher in the future, new research has demonstrated.
Solar evaporator offers a fresh route to fresh water
16 Apr 2019 at 5:13am
Researchers have demonstrated a successful prototype of one critical component for affordable small-scale desalination: an inexpensive solar evaporator, made of wood.
Best in snow: New scientific device creates electricity from snowfall
15 Apr 2019 at 1:08pm
Researchers have designed a new device that creates electricity from falling snow, a first. The device is inexpensive, small, thin and flexible like a sheet of plastic.
Performance of perovskite solar cells: The interface makes the difference
12 Apr 2019 at 7:13am
Researchers look in detail at the interfaces in perovskite solar cells to understand the differences observed in their performance.
Renewables are a better investment than carbon capture for tackling climate c...
8 Apr 2019 at 8:40am
Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research. New research shows that resources that would be spent on developing and installing carbon capture technologies would be better invested in creating more solar panels and wind turbines and focusing on developing energy storage options to support these instead.
Mystery of negative capacitance in perovskite solar cells solved
5 Apr 2019 at 5:09am
Scientists reveal the origin of apparently high and even negative capacitance values observed in perovskite solar cells.
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.
