New PV cell generates electricity from IR and UV light

(PhysOrg.com) -- A prototype of a new type of photovoltaic (PV) cell that generates electricity from visible, infrared and ultraviolet light has been demonstrated by a group of Japanese scientists. It could lead to the development ...

New record achieved in terahertz pulse generation

A group of scientists from TU Wien and ETH Zurich have succeeded in their attempts to generate ultrashort terahertz light pulses. With lengths of just a few picoseconds, these pulses are ideally suited to spectroscopic applications ...

Researchers demonstrate new technique for generating electricity

Research scientists at VTT Technical Research Centre of Finland have demonstrated a new technique for generating electrical energy. The new method can be used in harvesting energy from mechanical vibrations of the environment ...

Toward a new generation of paper-thin loudspeakers

In research that may redefine ear buds, earphones, stereo loudspeakers, and other devices for producing sound, researchers in China are reporting development of flexible loudspeakers thinner than paper that might be inserted ...

A SHARP new microscope for the next generation of microchips

(PhysOrg.com) -- Moore’s Law, hardly a law but undeniably a persistent trend, says that every year and a half, the number of transistors that fit on a chip roughly doubles. It’s why electronics – from smart ...
