Many PV's degrade to 50% or less of their ORIGINAL efficiency, which is usually pretty low--around 10% 1) What is the efficiency of these thin films?

When they actually ship and with a warranty for ten or twenty years I will believe it. Until then they are just like the hundreds of other companies whose main output is press releases.
