Controlling organic semiconductor band gaps by electron-acceptor fluorination

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. … read more

Renewable energy is common ground for Democrats and Republicans

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. … read more

The Duck Curve: Utilities’ Growing Challenge to Solar Adoption

Since 2008, the U.S. has seen a veritable explosion of not just residential solar, but commercial and utility-scale installations as well, enjoying a ridiculously high annual growth rate of 54% over the last 10 years. As of September 2018, there is now 58.3 GW of solar installed in the U.S., with the vast majority –23GW […]

Opening communication lines between propulsion and airflow poses new questions

On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the more

Efficiently turning light into electricity

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. … read more

New technique for turning sunshine and water into hydrogen fuel

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. … read more

Metal leads to the desired configuration

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. … read more

Off-Grid Solar and the Path to Universal Access

One in seven people around the world live without access to electricity, and that is leaving a devastating human toll. In Sub-Saharan Africa, where over 60% of these affected populations live, people are dying from basic ailments because vaccines cannot be refrigerated; lack of lighting for school-work leaves the region with the lowest literacy rate […]

Artificial enzymes convert solar energy into hydrogen gas

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. … read more

Windier wind farms

Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind more

Boosting the efficiency of silicon solar cells

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. … read more

Large-scale US wind power would cause warming that would take roughly a century to offset

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. … read more

The 5 States Making Solar Mainstream

Solar energy is more mainstream now than ever before thanks to rapid innovations in the industry that have slashed prices of solar panels over the past several years. The rapid maturation of the solar market in the U.S. has been fueled primarily by a handful of states who have made the sector’s growth a top […]
