I feel like I should clarify because the article didn't do a good job at explaining: perovskite is a kind of structure, not a particular material. They have the generic formula ABX~3~ (where A and B are different kinds of cations and X is some kind of anion), although not everything with the formula is a perovskite.
Simple perovskites include some lead-containing materials like lead titanate, but also lead-free materials like barium or strontium titanate. And in general there are a lot of different kinds of perovskites, especially because some of the structural sites can be filled by small organic molecules instead of pure elements.
Edit: I think I was misreading the journal article before my edit (it's early I'm not awake yet lol). I had said it looks like they're using a lead-based perovskite but actually I can't tell what exactly they're using with a quick skim. The article is very review-y, the formula I thought they were using is from another paper. I'll have a more thorough look later.
Edit 2: It's a review paper, and the way it was described in the linked news article is kinda misleading. Its not specifically about this company's particular composition or architecture.
The paper mentioned.
I'm confused as hell. This looks like just a general review of perovskite solar cells. Where in there is the direct connection to this particular product?
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.
