"Someone will buy their plants and probably go into the same production process." Unlikely. The only way this would make sense is if the company were grossly mismanaged and the technology was decent. It wasn't- the tubes needed 165 cells per tube- and they weren't a lot of area. That's a lot of connections where I suspect that equivalent watts out of silicon probably needed a single panel or less. I don't know if the company was mismanaged, but having a working line and people on it, and orders would suggest that it wasn't. There just wasn't any profit in the foreseeable future given the pricing of cells with the Chinese dumping. A chunk of this was the worries about silicon pricing- that silicon was thought to be expensive. Well, it really isn't, and there's plenty of the stuff. Thin film CIGS cells like Solyndras were supposed to offer decent efficiency, although not as good as silicon, but be less expensive because they used less material. In theory, CIGS cells could exceed the efficiency of silicon too, but since silicon is getting close to mature technology (it's closing in on the Shockley efficiency limit of 29% - I think the best silicon cells have exceeded 23% efficiency (don't hold me to his, it's off the top of my pointy head) so there's really not that much more to go. Pretty sure CIGS theoretical efficiency is around 40%. Sam
