IBM needs to do some research... market research. Run of the mill monocrystalline is regularly hitting 19%. High end, is hitting 23% and that is in production. Multijunction are 30%+ in the lab ... these are all one sun number. CIGS is currently 13.5% in near production ready and by the time this gets to 11% I would expect production CIGS to be in the 14-15% range.

IBM says that its new ultra-cheap thin-film solar cell formulation could someday result in efficiencies as high as 20 percent, which is as high as ultra-expensive GaAs solar cells for space apps. Is 10-to-20 percent high enough to knock silicon and gallium arsenide out of the running?
