Yeah as far as I can tell without a close read of the paper – which I just don't have time to do – it's a review paper that just happens to have been written by some of the people involved in this commercial endeavor. (I imagine they don't want to share their proprietary composition and architecture.) It seems like the reporter covering this didn't catch the distinction.
To my previous comment, this means we really have no idea if they're using a lead-containing composition or not. Like I mentioned, perovskites are a large class of materials. Since the review paper has a section on the challenges around lead containing compositions I'd hope they're not using lead, but who knows 🤷♂️
Ah, okay.
