Basically a highly-inefficient method of converting energy. I've looked at the article and the pictures, and what I see is basically slapping a solar cell with a gold mirror backing right near a hot ribbon of graphite - eg we're trying to use highly inefficient incandescence to generate light. Want to know what works better? Just the simple mix of gold into the p-n junction matrix and finger lines. Takes a silicon solar cell up to about 35% efficiency when properly doped into the junction material. This technology? Well, given incandescence isn't going to break ~30% efficiency (excepting in the IR-glass-sandwiched tungsten filament) you're literally just wasting energy. Best we've seen in general incan is ~12% efficiency, so enjoy your 30-ish percent of that (4%). You're better off with other technologies. This is neat, but you're looking at pretty much over-simulating the conditions of a solar cell welding line, which means that solar cell is going to likely bust over time under the heat stress. I foresee tons of problems with this tech, from the incan ribbon breaking to the cell harvesting energy breaking from the heat/cool cycling.
