Let's see if the research pans out and whether the solar cells can be manufactured for a reasonable cost. For terrestrial applications, cost per watt over a period of time may be more important than efficiency. By that, I mean if you can use an inexpensive technology like amorphus silicon to produce cheap electricity, even at low efficiency, it might be better than a much more expensive technology.
In space, efficiency and resistance to solar degradation is much more important than cost.
