1. Whoopsie, the "C" in CIGS is for copper. But hey, selenium is plenty toxic enough.

If any CIGS cells are destroyed by burning, I wouldn't want to be within miles of that smoke. Same with anything containing cadmium.

Oooh, on further reading it turns out that most CIGS cells are capped with a "buffer" layer of CdS (WHY CdS I don't know). So toxic cadmium AND toxic selenium in one delightful sandwich.
