Taiwanese scientists develop high

I still don't get it. Light paper centered on concord on making a bunch of Fresnel lenses practically? Their idea of GaAs/CIGS/Xtalline Si cells 1.1 mm square at a time to catch the conc. sun and polycrystalline Si or clear/void for agriculture around it is good. I hope the practical versions turn out as good; all fun to cover a large area until the cover also has to track the sun and permit pollination and harvest. How do you even make low profile heatsinks for those 1.1 mm sq. cells?
