What part of QD solar cells do not exist yet can you not understand??
There are universities worldwide and other companies spending hundreds of millions of dollars on research and they all say they are at least 3-5 years from having a commercial product, yet you believe QTMM with their two dollar and 98 cent research and development budget and one grad assistant working, has one ready to go. Oh yeah, they've been claiming that since 2009!!! Of course they will have the great researchers at Amtronics helping them, they are of course well known for all their cutting edge developments.
What's more realistic, that QTMM and Amtronics are 5+ years ahead of the world, or that Squires and Robinson pulled one off on the Indians??
