“Researchers claim achievement of new record photovoltaic conversion efficiencies for perovskite-based solar cells by spicing them up with a little capsaicin,” writes Slashdot reader ffkom, adding: “Of course everyone who loves to eat chilis already knew capsaicin energizes you to record levels.” The researchers have published their findings in the journal Joule. From the report: Perovskite solar cells (PSCs) suffer from…

Cerebras’ Wafer-Size Chip Is 10,000 Times Faster Than a GPU
An anonymous reader quotes a report from VentureBeat: Cerebras Systems and the federal Department of Energy’s National Energy Technology Laboratory today announced that the company’s CS-1 system is more than 10,000 times faster than a graphics processing unit (GPU). On a practical level, this means AI neural networks that previously took months to train can now train in minutes on the…
Semi-Transparent Solar Cells Could Make Greenhouses Self-Sufficient
An anonymous reader quotes a report from New Atlas: Organic solar cells (OSCs) have a few advantages over other designs. They still collect energy from sunlight, but can be made more flexible, transparent (or at least semi-transparent) and can be tuned to only absorb certain wavelengths of light. That potentially makes them perfect for greenhouse roofing — they can let most…
New Electric Battery Design Can Charge an Electric Vehicle In 10 Minutes
ted_pikul writes: Penn State University researchers report in the journal Joule that they’ve designed an electric battery that can charge an EV for 200 miles in about 10 minutes. The key to their approach is quickly heating the nickel foil-covered battery to a high temperature and more slowly cooling it to ambient temperatures. The researchers report that in addition to the…
New Device Harvests Energy In Darkness
In new research published on Thursday in the journal Joule, Dr. Raman, an electrical engineer at the University of California, Los Angeles, demonstrated a way to harness a dark night sky to power a light bulb. The New York Times reports: His prototype device employs radiative cooling, the phenomenon that makes buildings and parks feel cooler than the surrounding air after…
