Quite a tad disappointed with the panelists today. When I mentioned the use of OPV, it was dismissed as being too immature a technology, and cited that only 1 company makes OPV. But a cursory search via google showed at least 4 companies! What's more, DARPA is actually looking towards OPV for its field energy generation! The forecasted potential for OPV is like 40c/watt peak vs $4 / watt peak for Si cells! And this guy somehow manages to make OPV sound like some useless technology meant mainly for toys and gadgets?!

And what was worse...

"By the time we need batteries to store excess electrical power from solar cells, I would be long dead!"

I didn't know scientists talked like that. V disappointed.
