High-quality mono-silicon crystal grown at low cost for solar cells

A joint research team in Japan has developed a “single-seed cast method,” a new casting method making it possible to grow high-quality mono silicon at low cost. New casting method may facilitate the return of a market-competitive solar cell industry.

Evaporation-powered motor and light

Scientists designed shape-changing composites that used evaporation to power locomotion and generate electricity.

Digestible batteries needed to power electronic pills

Imagine a ‘smart pill’ that can sense problems in your intestines and actively release the appropriate drugs. We have the biological understanding to create such a device, but we’re still searching for electronic materials (like batteries and circuits) that pose no risk if they get stuck in our bodies. Now researchers present a vision for creating safe, consumable electronics, such as those powered by the charged ions within our digestive tracts.

X-rays reveal details of plastic solar cell production

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers have now managed to observe these processes in real time. Their findings could help to improve the efficiency of organic solar cells.

Superflare: Sun could release flares 1000x greater than previously recorded

The Sun demonstrates the potential to superflare, new research into stellar flaring suggests. New research has found a stellar superflare on a star observed by NASA’s Kepler space telescope with wave patterns similar to those that have been observed in solar flares. Superflares are thousands of times more powerful than those ever recorded on the Sun, and are frequently observed on some stars.

Borrowing from whales to engineer a new fluid sensor

Researchers have borrowed from biological structures called tubercles that humpback whales use to maneuver in the ocean to make a piezoelectric energy harvester for use as an airflow or fluid speed and direction-sensing device.

Pushing the limits of solar cells

Scientists have introduced a new strategy for generating more efficient solar cells.
