Otherwise, the slides look like hopeful hype. Others, with manufacturing lines, already claim $.80/W modules, which indicate its a catch-up game already.

Check the Picasa slideshow for the SilFoil efficiency bubble around 16%. All Nanogram Solar said was mc-Si efficiency bordering on monocrystalline silicon. I believe Nanogram Solar mentioned they are making the six (6) inch square mini modules in 8 to 10 unit batches. Nanogram Solar did not mention an efficiency number.
