The efficiency is probably much lower. Nanosolar is already doing flexible solar arrays, albeit at only 10-15% efficiency, but it’s free energy essentially, and silicon is where most of the money is at in these arrays, along with mounting.

If one were to believe Nanosolar's claims, they should be ruling the world by now.
