Finding the best light-harvesting chemicals for use in solar cells can feel like searching for a needle in a haystack. Over the years, researchers have developed and tested thousands of different dyes and pigments to see how they absorb sunlight and convert it to electricity. Sorting through all of them requires an innovative approach.

Now, thanks to a study that combines the power of supercomputing with data science and experimental methods, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Cambridge in England have developed a novel “design to device” approach to identify promising materials for dye-sensitized solar cells (DSSCs). DSSCs can be manufactured with low-cost, scalable techniques, allowing them to reach competitive performance-to-price ratios.

The team, led by Argonne materials scientist Jacqueline Cole, who is also head of the Molecular Engineering group at the University of Cambridge’s Cavendish Laboratory, used the Theta supercomputer at the Argonne Leadership Computing Facility (ALCF) to pinpoint five high-performing, low-cost dye materials from a pool of nearly 10,000 candidates for fabrication and device testing. The ALCF is a DOE Office of Science User Facility.

Abstract

The aim of the passive igloo project is to explore the possibilities of creating an ecological and self-sufficient habitat by using sound constructive measures and renewable energy resources to guarantee thermal comfort in the most severe cold climates.

The passive igloo is a self-sufficient housing module built into a polar exploration sailboat to accommodate a crew of 2 to 6 people in conditions of severe cold to live and work. In order to test the passive igloo, the boat was voluntarily trapped in the ice in North West Greenland during the winter of 2015–2016 and monitored during the 10 months of ‘stationary navigation’.

Porsche made headlines for a battery it says can be charged with 400 kilometers (250 miles) of range in 15 minutes. If Piëch’s claims about a 4:40 charge hold up, Engadget pointed out, they’ll blow Porsche’s technology out of the water.

“We have developed a sports car that we ourselves would like to buy, and we talked for a long time to many enthusiasts about what was missing on the market,” co-founder Toni Piëch said in the press release. “We want to offer a modern classic that isn’t subject to consumer cycles. The driver of this sports car should enjoy any minute they can spend in the car.”

China says it is working to develop a solar energy plant in space that could one day beam enough power back to Earth to light up an entire city.

If scientists can overcome the formidable technical challenges, the project would represent a monumental leap in combating the Earth’s addiction to dirty power sources which worsen air pollution and global warming.

A space-based solar power station could also provide an alternative to the current generation of earthbound and relatively ineffective renewable energy sources.

Leslie Dewan wants to revive technology from the 1960s to solve the problem of climate change today.

A way to speed up quantum computer tech progress has arrived from Intel. If you are interested in following the waves and advances in quantum computing, then get familiar with this word trio: Cryogenic Wafer Prober. Before their design, the electrical characterization of qubits was slower than with traditional transistors. Even small subsets of data might take days to collect.

Drug development. Chemistry. Climate change. Financial modeling. Scientists in all areas look forward to more advancements to push quantum computers to the frontlines. Speeding progress could also mean speeding up advancements in science and industry.

“Quantum computing, in essence, is the ultimate in parallel computing, with the potential to tackle problems conventional computers can’t handle,” said Intel.

Widespread and sometimes drastic marine oxygen declines are stressing sensitive species—a trend that will continue with climate change.

When was the last time you thought about your breathing? Take a breath right now and think about it. You breathe because you need oxygen, a gas which makes up 21 percent of the Earth’s atmosphere. All that oxygen has to come from somewhere. You might already know that it comes from photosynthetic organisms like plants. But did you know that most of the oxygen you breathe comes from organisms in the ocean?

That’s right—more than half of the oxygen you breathe comes from marine photosynthesizers, like phytoplankton and seaweed. Both use carbon dioxide, water and energy from the sun to make food for themselves, releasing oxygen in the process. In other words, they photosynthesize. And they do it in the ocean.
