Wow - this is a totally different approach than crystalline silicon, and could be much cheaper to produce as well as more efficient. Something new is going to be required to do much better than 35% efficiency, as you can only do so much lining up the band-gap of semiconductors. On another note, it's nice to see that crystalline silicon PV is perceived to be so successful that people are lining up to comment on how a dramatic improvement in power density and cost wouldn't really matter.
