solar update, page-2

Thanks Geddo for the info,I can understand why they don't want to release anything until the patents are in place, and if they said "When the announcement is made, you will not be disappointed" then I believe they already know the efficiency which was either tested by NREL or HEU,or both perhaps? was the real reason they employed two sources to do the testing, really because they are almost unbelievable?
When you look at the chart on page 113 of the PDF provided the other day and look at what they call 4th generation,i.e. low cost high efficiency cells, look where it sits? is it 50% or better for a 5-6 junction system? and up to a limit of 70% for maximum efficiency at the junction limit?
