Promising. Nanowires seems to be the answer to many things lately. There is also the promising development of nanowire use in battery technology.

Hairy Solar Panels Could Result From Nanowire Breakthrough

The aim is to produce flexible, affordable solar cells composed of Group III-V nanowires that, within five years, will achieve a conversion efficiency of 20 percent. Longer term, he says, it's theoretically possible to achieve 40 percent efficiency, given the superior ability of such materials to absorb energy from sunlight and the light-trapping nature of nanowire structures. By comparison, current thin-film technologies offer efficiencies of between 6 and 9 percent.

Nanowires seems to be the answer

You didn't spot the important words! Well, the words that are important to a researcher anyway.

The aim .... five years ...

The people working on this need somebody to fund them, ideally for the rest of their working lives but five years is a good start!

What questions do they answer?
