Two layers of indium gallium nitride, one tuned to a band gap of 1.7 eV and the other to 1.1 eV, could attain the theoretical 50 percent maximum efficiency for a two-layer multijunction cell. (Currently, no materials with these band gaps can be grown together.) Or a great many layers with only small differences in their band gaps could be stacked to approach the maximum theoretical efficiency of better than 70 percent.

Interesting.

Now watch the democrats immediately turn this into the "we don't any oil at all..... (Except for the greed of the Texas oil companies we would be free at last!)"

(Please open page 6969 of your "Give peace a chance" hymnal, and begin singing "Kumbuyacomebuya".)
