At 39.7% efficiency for a multi-junction solar cell, researchers at the Fraunhofer Institute for Solar Energy Systems have exceeded their own European record of 37.6% which they achieved just a short time ago. III-V semiconductor multi-junction solar cells are used in photovoltaic concentrator technology for solar power stations.

There is an excellent article from Dan Hahn, over at Solar Power Rocks digging into how oil and coal contributions affects the way US Senators vote on renewable energy legislation.
There is the obvious split down the middle with regard to Republicans and Democrats, but there are also some very interesting insights the funding and voting [...]

Engineers have devised a new way to slice thin wafers of the chemical element germanium for use in the most efficient type of solar power cells. They say the new method should lower the cost of such cells by reducing the waste and breakage of the brittle semiconductor.
