Re: QE and well capacity

If we increase QE without increasing well size, there is no
improvement in SNR, but we achieve that SNR with fewer photons.

How is signal defined? Ultimately, the signal we are interested in is the light going through the lens. In that sense, the SNR is higher with higher quantum efficiencies, even with the same full-well capacity.
