New material, manufacturing process use sun's heat for cheaper renewable elec...
18 Oct 2018 at 9:51am
Scientists have developed a new material and manufacturing process that would make one way to use solar power -- as heat energy -- more efficient in generating electricity.
Controlling organic semiconductor band gaps by electron-acceptor fluorination
17 Oct 2018 at 5:08am
Researchers synthesized a fluorinated electron-acceptor for use in organic semiconductors. The high electronegativity of the fluorine substituents enhanced the electron-accepting properties of the widely used electron-acceptor. The power conversion efficiency of a thin film solar cell based on the fluorinated product was shown to be significantly higher than that of a cell containing an unmodified analogue. The synthesized material could be applied in thin film organic solar cell devices.
Renewable energy is common ground for Democrats and Republicans
16 Oct 2018 at 11:24am
While conservatives and liberals tend to disagree on many environmental issues, they both view the development of solar power and other forms of renewable energy as financially savvy and a step towards self-sufficiency.
Efficiently turning light into electricity
11 Oct 2018 at 7:37am
Perovskites form a group of crystals that have many promising properties for applications in nano-technology. However, one useful property that so far was unobserved in perovskites is so-called carrier multiplication -- an effect that makes materials much more efficient in converting light into electricity. New research has now shown that certain perovskites in fact do have this desirable property.
New technique for turning sunshine and water into hydrogen fuel
11 Oct 2018 at 7:36am
Researchers have developed new photocatalyst synthesis method using Magnesium hydride (MgH2) and Titanium dioxide (TiO2). The result is expected to contribute to hydrogen mass production through the development of photocatalyst that reacts to solar light.
Metal leads to the desired configuration
9 Oct 2018 at 8:49am
Scientists have found a way to change the spatial arrangement of bipyridine molecules on a surface. These potential components of dye-sensitized solar cells form complexes with metals and thereby alter their chemical conformation.
Artificial enzymes convert solar energy into hydrogen gas
4 Oct 2018 at 12:54pm
Researchers have synthesized an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize the cell's own energy, and thereby enable hydrogen gas to be produced from solar energy.
Boosting the efficiency of silicon solar cells
4 Oct 2018 at 8:25am
A solar cell's efficiency indicates what percentage of the solar energy radiated into the cell is converted into electrical energy. The theoretical limit for silicon solar cells is 29.3 percent due to physical material properties. In a new article, researchers describe how this limit can be abolished.
Large-scale US wind power would cause warming that would take roughly a centu...
4 Oct 2018 at 8:25am
Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the atmosphere.
Emissions-free energy system saves heat from the summer sun for winter
3 Oct 2018 at 6:03am
Researchers have made strides towards the development of a specially designed molecule which can store solar energy for later use.
Supersizing solar cells: Researchers print module six times bigger than previ...
2 Oct 2018 at 7:28am
A perovskite solar module the size of an A4 sheet of paper, which is nearly six times bigger than modules of that type reported before, has been developed by using simple and low-cost printing techniques.
Eco-friendly nanoparticles for artificial photosynthesis
1 Oct 2018 at 7:19am
Researchers have developed a nanoparticle type for novel use in artificial photosynthesis by adding zinc sulfide on the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight -- a sustainable source of energy. They introduce new eco-friendly and powerful materials to solar photocatalysis.
Perovskite solar cells leap toward commercialization

Scientists' research on perovskite solar cells indicates a promising future towards sustainability.
Device that integrates solar cell and battery could store electricity outside...
27 Sep 2018 at 11:55am
Scientists have harnessed the abilities of both a solar cell and a battery in one device -- a 'solar flow battery' that soaks up sunlight and efficiently stores it as chemical energy for later on-demand use. Their research could make electricity more accessible in remote regions of the world.
A self-powered heart monitor taped to the skin
26 Sep 2018 at 11:08am
Scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor. In this study, they directly integrated a sensory device, called an organic electrochemical transistor -- a type of electronic device that can be used to measure a variety of biological functions -- into a flexible organic solar cell. Using it, they were then able to measure the heartbeats of rats and humans under bright light conditions.
