Agree though, if 60-70% efficiency can be cost effectively achieved, the world's going solar

Actually I think 20% is the newer typical efficiency, true, BUT, they need to be a low cost/Kw output, that is why panels efficiency vary so much, because in the end, a low output low cost panel is just as cost effective as a higher output higher cost panel. There is obviously a limit on the low end, as you run into area constraints, and would end up being MORE expensive.
Agreed as well, we need about 60-70% efficiency like you said to really get things moving with solar, and to meat energy use.
