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?
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
