SOLAR - Solar PVs 44% Efficiency Record, Thanks To NREL & Solar Junction

Here's a great solar PV story from the good folks over at NREL (note that we've already covered Solar Junction's 44% solar cell efficiency record, but this post below goes above & beyond that first one):An operator inspects a photolithography tool used to manufacture high-efficiency Solar Junction concentrator solar cells. NREL's pioneering multijunction work led to the Solar Junction SJ3 solar cell with tunable bandgaps, lattice-matche .
