Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the ultimate conversion efficiency can never exceed 34 percent for a single optimized semiconductor junction. Now, researchers at MIT have shown that there is a way to blow past that limit as easily as today's jet fighters zoom through the sound barrier...

Solar Cells Developed That Peel-And-Stick To Virtually Anything
2013-04-17 05:37:09

redOrbit Staff & Wire Reports - Your Universe Online Stanford University and the Department of Energy´s National Renewable Energy Laboratory (NREL) have developed a peel-and-stick solar cell that could one day be used to charge mobile phones and power a variety of other small devices. Peel-and-stick, or water-assisted transfer printing (WTP), technologies were developed by the Stanford group, and have been used before for nanowire based electronics. However, the Stanford-NREL...

Researchers Look To New Process To Harvest Solar Energy
2013-02-25 15:25:57

Peter Suciu for redOrbit.com — Your Universe Online Since the seventh century B.C., mankind has looked to the power of the sun to provide an energy source. In the earliest days, humans used glass and mirrors to concentrate the sun's rays to make fire. Later, around the first century A.D., the Romans discovered large south facing windows could help let in the sun´s warmth. There's even one infamous tale of Greek scientist Archimedes using bronze shields to reflect and focus...
