New Discovery Settles Debate About Photovoltaic Materials

Ames Laboratory scientists discovered evidence of the Rashba effect by using extremely strong and powerful bursts of light firing at trillions of cycles per second to switch on or synchronize a "beat" of quantum motion within a material sample; and a second burst of light to "listen" to the beats, triggering an ultrafast receiver to record images of the oscillating state of matter.

Scientists have theorized that organometallic halide perovskites-- a class of light harvesting "wonder" materials for applications in solar cells and quantum electronics-- are so promising due to an unseen yet highly controversial mechanism called the Rashba effect.

Often and Little, or Rarely and to the Full?

When supplying energy the method of its delivery is as important as its quantity. You probably won't manage to boil the water for your tea with a cigarette lighter. Here, PhD student Yirui Zhang illustrates this principle.

If we were talking about food, most experts would choose the former, but in the case of energy storage the opposite is true. It turns out that more energy can be stored by charging less often, but right up to 100%. At least, this is the conclusion arrived at from research carried out by a team of scientist

106,000 Jobs in Clean Energy Lost in March Due to COVID-19 Economic Crisis
More than 106,000 clean energy workers lost their jobs in the month of March, and hundreds of thousands more clean energy job losses are projected in the coming months. That’s according to a new analysis of unemployment data released today by E2 (Environmental Entrepreneurs), the American Council on Renewable Energy (ACORE), E4TheFuture and BW Research Partnership. The analysis of Department of Labor data found that 106,472 workers in clean energy occupations filed for unemployment benefits last month, wiping out all 2019 clean energy job gains across renewable energy, energy efficiency, clean vehicles, energy storage and clean fuels.
