Latest solar cells Stories
Researchers at the University at Buffalo are developing a technique that could allow for solar panels to be painted on some day.
University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors.
“When designing next generation solar energy conversion systems, we must first develop ways to more efficiently utilize the solar spectrum,” explained Lane Martin, whose research group has done just that.
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.
Stanford University and the Department of Energy’s National Renewable Energy Laboratory 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.
Nanowires could be the answer for constructing solar panels with less materials and lower costs.
