Adding from communist’s comment, if they don’t stay efficient very long, how easy are them to recycle? Apparently they use common materials, but does that necessarily means it’s common to recycle?
It’s a metal salt, basically. The best ones according to the review cited use lead and halides, with formamidinium, methylammonium or Cesium. So, pretty easy to recycle, you could turn it back into the original ingredients with basic electroplating.
Whatever packaging might be more of an issue, but that’s implementation-specific.
