Traditional Photovoltaic Solar Cells Have an Inherent Limit on The Efficiency
Jan 21, 2014
Traditional photovoltaic solar cells have an inherent limit on the efficiency at which they can convert sunlight into energy. This limit—based on the bandgap of the material used and known as the Shockley-Queisser limit—is about ...

A New Approach to Harvesting Solar Energy, Developed by Mit Researchers
Jan 19, 2014
A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. ...
