I hope this makes it into production at some point. I had a lot of hope for the CIGS stuff[1] but they haven't been able to get to the point where they have enough efficiency at at low enough cost to flip them into the mainstream to get mass market economics of scale to work for them.

CIGS, like CdTe, has always been limited by material economics. As demand goes up, the world economy’s limited production of these exotic byproducts can’t keep up.

Believe it or don’t, the last time I crunched the numbers, it was the Selenium in CIGS that they’re having the most trouble unlocking more of.

That is surprising, the early 2000's there was a huge uproar over all of the selenium runoff going into the San Francisco bay. At the time I wondered if there was an economic use for selenium and if extracting it from water was economically feasible.
