Power/Performance Bits: Aug. 15


Solar sunglasses Researchers at the Karlsruhe Institute of Technology (KIT) developed sunglasses with colored, semitransparent organic solar cells applied onto the lenses capable of supplying a microprocessor and two displays with electric power. The solar cell lenses, perfectly fitted to a commercial frame, have a thickness of approx. 1.6 millimeters and weigh about six grams, just like th... » read more

Power/Performance Bits: Sept. 3


Flexible, organic solar cells Work by a team of chemical engineers at Penn State and Rice University may lead to a new class of inexpensive organic solar cells. If solar cells could be made as easily as posters or newspapers are printed, sheets of organic solar cells could be made, representing a fundamental shift in the way solar cells are made, the researchers said. Today, most solar c... » read more
