Where's the evidence for that? The major point was that Solyndra bet on the wrong horse with CIGS; they were unknowingly doomed to fail from the start.
What happened with CIGS? There was a privately funded CIGS company here in Austin TX that also didn't make it (even though the founders and investors were solid) and I've not gotten a straight answer as to why - esp. confusing because the first quals looked very good.
Well, nothing. That's basically the point. Or, at best very little happened with it. "It wasn't getting cheaper faster than silicon was" is the most concise answer I can come up with.
