I'm waiting for full spectrum (multilayer) solar cells - so much light is wasted by current solar, they cherry pick only the green-blue parts of the spectrum. Need ones that harvest deep infrared to short ultraviolet. There's not so much short UV, but the little that does arrive packs a wollop in much higher energy levels.
