Sounds fishy to me. The current sensors have about 50% QE. This means that one can only increase it twice, not 1,000 times.
In principle, "sensitivity" is not a well defined term when it comes to digital sensors. They are photon counting machines, missing every other photon, roughly speaking.
Yes, your thinking mirrors mine. Perhaps its a deeper electron well that holds more photons, but that implies a longer exposure. The description of "Wang said the key to his new sensor is the use of
"light-trapping" nanostructures that use graphene as a base. The nanostructures hold onto light-generated electron particles for much longer than conventional sensors." is a bit vague and does not explain the predicted usefulness for consumer imaging.
I can see it useful for astronomy and night time imaging, perhaps even satellite imaging, but for a camera that is used to do high fps or video, I do not understand.
