asoduk writes "The inverted metamorphic triple-junction solar cell was designed, fabricated and independently measured at NREL. The 40.8 percent efficiency was measured under concentrated light of 326 suns. One sun is about the amount of light that typically hits Earth on a sunny day. The new cell is a natural candidate for the space satellite market and for terrestrial concentrated photovoltaic arrays, which use lenses or mirrors to focus sunlight onto the solar cells."

Concentrated Sunlight (Score:1)
Before anyone starts complaining that using lenses to concentrate sunlight on a solar cell like this would drive up the cost, yes and no. A fairly inexpensive plastic or glass Fresnel lens [wikipedia.org] could be used, and its a whole lot cheaper than silicon wafer photovoltaic cells. For 40% efficiency, I'd buy it.
