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 used to work on hybrid perovskite for solar cells, during my PhD, a few years ago. The problem with theses materials was their short lifetime (some thousands of hours of sun exposition) and chemical instability, which made them unsuitable for "real life" uses, back then (but suitable to get high impact-factor papers...). Is that still a problem?

Isn't thousands of hours enough for many cameras?

If it's a moving mirror camera* and it's used to take stills it's probably fine, as the sensor is only exposed for a fraction of a second per image.
If you want to film with it or put it in a phone, where it's exposed all the time, it would certainly not be enough.

* I have no clue what they are called in english

Digital single-lens reflex, aka DSLR if that's what you mean by moving mirror
