If we can just find out what solar companies they're selling this to... of the 3 that own their own polySI production... I'd know who's stock to buy [more of] :)

If the patent is legit, and there aren't other patents blocking something vital then anyone can do it, I think.

I'm not a patent attorney, but 20 years is the life of a patent.

In any case, this is fantastic news. That should translate into half price panels or so sooner or later.

Here is the patent, in case you want to read it yourself.

I'm not a patent attorney, but 20 years is the life of a patent.

I thought it was 17 years.

I can think of two possible explanations, either or both (or neither) of which may be true:

1. The claims of superior economics are exaggerated.

2. They've made recent key improvements to the technology that both extend the IP and make the process workable, whereas it wasn't before.

The latter explanation has some support in the Red Herring article, where it mentions that the SRI scientists have "updated" the technology.

According to some newly released research, PV solar panel use in homes is due to soar in the next five years:

But you all knew that, didn't you!

Actually, patents used to be in effect for 17 years from the date of issue. Starting 1995, it changeed to 20 years from date of filing. But that works out to be about the same thing, since there's usually a 2 or 3 year interval between filing and issue.

Feels like more and more things are using silicon. Lower prices is a great thing.
