This is very exciting, what I've heard is usually a far lower conversion rate of about 10% to 15% for average solar cells in normal conditions. I think this has to do also with the arc of the sun as "it moves" (we really do of course) across the sky, and the panels work best when the surface is aimed perpendicular to the rays.

Anyway, I'm looking forward to innovations like this comming to market, especially as sunlight is not so strong in Ireland and it is often cloudy in the west.
