Perovskite-based image sensors promise higher sensitivity and resolution than silicon (techxplore.com)

They use stacked transparent color sensors, like Foveon camera sensors used to.

In numerous experiments, the researchers put the two prototypes, which differ in their readout technology, through their paces. Their results prove the advantages of perovskite: the sensors are more sensitive to light, more precise in color reproduction and can offer a significantly higher resolution than conventional silicon technology.

The fact that each pixel captures all the light also eliminates some of the artifacts of digital photography, such as demosaicing and the moiré effect.

I mean, lead is a very common element and can have many legitimate uses. If we're talking about using some amount of lead in a camera sensor, do understand how tiny camera sensors are. This is likely a very insignificant amount of lead. And it will be fused into this sensor, it's not likely to ever leave the confines of the component's plastic casing, behind a lens, with a phone. That's very different from say, mixing it into gasoline and burning it.
