Scientists discover photovoltaic nanotubes
An international team of researchers led by the University of Tokyo has discovered a new material which, when rolled into a nanotube, generates an electric current if exposed to light. If magnified and scaled up, say the scientists, the technology could be used in future high-efficiency solar devices.
Waste heat is not cool, say US scientists
Engineers at the University of Utah have developed a tiny device which they say could increase the performance of PV panels and other electronic devices by converting energy lost as heat back into electricity.
