Solar cells must emit light to attain perfection, research suggests
Researchers at the University of California-Berkeley claim to have hit upon a counterintuitive means of boosting the efficiency of flatplate solar cells by making them emit light. “What we demonstrated is that the better a solar cell is at emitting photons, the higher its voltage and the greater the efficiency it can produce,” said principal researcher, UC Berkeley Professor of Electrical Engineering Eli Yablonovitch.

Universal Real-Time Translator
AT&T is bringing the universal translator to an app store near you. Well, Granted, it isn’t quite universal yet. For now, the AT&T Translator is capable of seven languages. So far the app supports English, Chinese, French, German, Italian, Japanese and Spanish. It seems reasonable to assume that if the app catches on that more languages will eventually be added.
The app was developed at AT&T Research Labs, using both AT&T Watson and AT&T Natural Voices speech technologies. Usage is simple. Speak a phrase into your device and the Translator converts what you’ve said into the language of your choice before broadcasting it to listeners. […]

MIT Engineers Design Fog-Free, Water-Repellent, Anti-Glare Glass
A new type of nano-structured glass can bounce water and dirt off its surface, cleaning itself and preventing fogging, according to MIT researchers. It eliminates glare, too, allowing light to penetrate with pure clarity. It could be used for anything from solar panels to future car windshields to new gadget screens. […]
